"[citation needed], In 1938, Farnsworth established the Farnsworth Television and Radio Corporation in Fort Wayne, Indiana, with E. A. Nicholas as president and himself as director of research. The second easiest reaction is fusing deuterium with itself. In 1923, the family moved to Provo, Utah, and Farnsworth attended Brigham Young High School that fall. This leads to an equation for power output. For this reason, the energy needed in a fusor system is higher than one where the fuel is heated by some other method, as some will be "lost" during startup. Farnsworth reasoned that he could build an electrostatic plasma confinement system in which the "wall" fields of the reactor were electrons or ions being held in place by the multipactor. In 2006, Farnsworth was posthumously presented the. She recommends that people focus on themselves, acknowledge their depression and understand what battle theyll have to wage. Yes, Murray Middle School collects Box Tops for Education. Farnsworth is one of the inventors honored with a plaque in the. [12] To date, the highest neutron flux achieved by a fusor-like device has been 3 1011 neutrons per second with the deuterium-deuterium fusion reaction. WebAn ebook (short for electronic book), also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Farnsworth always gave her equal credit for creating television, saying, "my wife and I started this TV." Hes looking to spread that message now across the world. One consequence of the thermalization is that some of the ions will gain enough energy to leave the potential well, taking their energy with them, without having undergone a fusion reaction. In either version there are two concentric spherical electrodes, the inner one being charged negatively with respect to the outer one (to about 80 kV). Second, there are the x-ray and neutron emissions that are possible. [10] Farnsworth held 300 patents, mostly in radio and television. Baird demonstrated his mechanical system for Farnsworth. Once her husband passed away, Hirsch focused her attention on writing and building her career, which allowed her work through the demons that hung on her shoulder. Improving Particle Confinement in Inertial electrostatic Fusion for Spacecraft Power and Propulsion. [24] Most recently, the fusor has gained popularity among amateurs, who choose them as home projects due to their relatively low space, money, and power requirements. [citation needed], George H. Miley at the University of Illinois reexamined the fusor and re-introduced it into the field. However, as with other fusion experiments, development into a power source has proven difficult. Families will then have the opportunity to visit 6th grade classrooms, meet teachers and support staff, and learn about middle school opportunities. [43], In 1932, while in England to raise money for his legal battles with RCA, Farnsworth met with John Logie Baird, a Scottish inventor who had given the world's first public demonstration of a working television system in London in 1926, using an electro-mechanical imaging system, and who was seeking to develop electronic television receivers. [2] [3] A variant type of fusor had been proposed previously by William Elmore, James L. Tuck , and Ken Watson at the Los Alamos National Laboratory [4] though they never built the machine. In the case of the fusor the electrons are generally separated from the mass of the fuel isolated near the electrodes, which limits the loss rate. [53], In 1999, Time magazine included Farnsworth in the "Time 100: The Most Important People of the Century". [7][30]:250254, Farnsworth Television and Radio Corporation was purchased by International Telephone and Telegraph (ITT) in 1951. Robert L. Hirsch, "Inertial-Electrostatic Confinement of Ionized Fusion Gases". The box tops are collected by the AVID program and are used for direct student funding. As the atoms are randomly distributed to begin, the amount of energy they will gain differs; atoms initially near the anode will gain some large portion of the applied voltage, say 15keV. [14] He won $25 in a pulp-magazine contest for inventing a magnetized car lock. These changes in speed make the cloud lose energy as light. [citation needed], Farnsworth also developed the "image oscillite", a cathode ray tube that displayed the images captured by the image dissector. WebHIGH SCHOOL. [50][52], Farnsworth's wife Elma Gardner "Pem" Farnsworth fought for decades after his death to assure his place in history. For a variety of reasons, energies on the order of 15keV are used. His design included ion beams to shoot ions into the vacuum chamber. This system developed in the 1950s was the forerunner of today's air traffic control systems. [50][59], Although he was the man responsible for its technology, Farnsworth appeared only once on a television program. When her husband discovered that his previously beaten brain tumor was back, her life took on a darker shade. In America alone, 9 percent of the country battles the issue, with 3.4 percent suffering from a major case of depression, according to WebMD. The video camera tube that evolved from the combined work of Farnsworth, Zworykin, and many others was used in all television cameras until the late 20th century, when alternate technologies such as charge-coupled devices began to appear. From there he introduced a number of breakthrough concepts, including a defense early warning signal, submarine detection devices, radar calibration equipment and an infrared telescope. She would just start crying in the middle of the day, and she didnt know why: I could feel that my hormones were taking me into a very dark place, she said. [10][11][12] Fusors have also become very popular for hobbyists and amateurs. [14] The business failed, and Gardner returned to Provo. But she only got to where she is now by overcoming depression as a teenager. He first demonstrated his system to the press on September 3, 1928,[25][29] and to the public at the Franklin Institute in Philadelphia on August 25, 1934. 360 Colborne Street, Saint Paul, MN, 55102. Whatever time I had, I made me a priority. My why. She is the reason I quit my sales job in February 2014 and went full time as a life coach. Because this gas is cheaper, it is the fuel commonly used by amateurs. WebSCHOOL NEWS. It was a sign that everything doesnt last forever, she said. WebSheboygan Area School District Updates Elementary School Report Cards November 7, 2022. In December 1965, ITT came under pressure from its board of directors to terminate the expensive project and sell the Farnsworth subsidiary. As you may be aware, our district internet system was compromised early in August and we are back up and running in PowerSchool. R.W. Bussard, "Method and apparatus for controlling charged particles". Copyright 2002-2022 Blackboard, Inc. All rights reserved. Sometimes that was only 15 minutes to 45 minutes, Hardy said. These particles will accelerate or decelerate as they move about. A 1983 United States postage stamp honored Farnsworth. WebPhilo Taylor Farnsworth (August 19, 1906 March 11, 1971) was an American inventor and television pioneer. Any power plant using fusion will hold in this hot cloud. While all three are Inertial electrostatic confinement (IEC) devices, only the last is actually a "fusor". Principal Michael Piscitelli piscitellim@guilderlandschools.net GHS Counseling Fax: 518-861-7067 GHS Nurses Fax: 518-861-5151 GHS Special Education Fax: 518-861-5152 He called this concept a virtual electrode, and the system as a whole the fusor. In the early 1930s, he investigated a number of vacuum tube designs for use in television, and found one that led to an interesting effect. My life's experiences have taught me a powerful lesson about the undervalued strength to be found in our raw human connections our relationships.. [54][55] In the course of a patent interference suit brought by the Radio Corporation of America in 1934 and decided in February 1935, his high school chemistry teacher, Justin Tolman, produced a sketch he had made of a blackboard drawing Farnsworth had shown him in spring 1922. Even those that scatter will simply take on a new trajectory, exit the grid at some new point, and accelerate back into the center again, providing the circulation that is required to a fusion event to eventually take place. That means the impact could spread far beyond the agencys payday lending rule. In January 1971, PTFA disbanded. Theater reviews by chief critic Jesse K. Green. [24], Farnsworth married Pem[19] on May 27, 1926,[12] and the two traveled to Berkeley, California, in a Pullman coach. In order to produce fusion events, the nuclei must have initial energy great enough to allow them to overcome this Coulomb barrier. WebA FarnsworthHirsch fusor is the most common type of fusor. T Farnsworth Archives (managed by Farnsworth heirs), Rigby, Idaho: Birthplace of Television (Jefferson County Historical Society and Museum), The Boy Who Invented Television; by Paul Schatzkin, Archive of American Television oral history interviews about Farnsworth including ones with his widow Elma "Pem" Farnsworth, Broadcast Pioneers of Philadelphia website, Global telecommunications regulation bodies, Faceted Application of Subject Terminology, https://en.wikipedia.org/w/index.php?title=Philo_Farnsworth&oldid=1121374840, All articles with bare URLs for citations, Articles with bare URLs for citations from June 2022, Articles needing additional references from July 2022, All articles needing additional references, Short description is different from Wikidata, Pages using infobox person with multiple employers, Articles with unsourced statements from July 2022, Articles with unsourced statements from December 2009, Creative Commons Attribution-ShareAlike License 3.0, Inventor of the first fully electronic television; over 169 United States and foreign patents. Chapman also spends her time doing more creative and artistic things, which limit her from falling into a dark place. They promptly secured a contract with the National Aeronautics and Space Administration (NASA), and more possibilities were within reachbut financing stalled for the $24,000 a month required for salaries and equipment rental. If they collide in the center, they can fuse. [citation needed], Things changed dramatically with the arrival of Robert Hirsch, and the introduction of the modified HirschMeeks fusor patent. Ions that fail to fuse pass through the center of the device and back into the accelerator on the far side, where they are accelerated back into the center again. Race/ethnicity was not collected for nonresident aliens. Wisconsin Madison, 1996. WebMelinda McBride, Principal (6-8) // Elias Oguz, Principal (9-12) 1495 Rice Street, Saint Paul, MN 55117. [10], Commercial startups have used the neutron fluxes generated by fusors to generate Mo-99, an isotope used for medical care. He is recognized in the Hall of Fame of the Indiana Broadcast Pioneerswhich notes that, in addition to his inventive accomplishments, his company owned and operated WGL radio in Fort Wayne, Indiana. The energy generated by fusion, inside a hot plasma cloud can be found with the following equation.[27]. For every volt that an ion of 1 charge is accelerated across it gains 1 electronvolt in energy. [citation needed], Many inventors had built electromechanical television systems before Farnsworth's seminal contribution, but Farnsworth designed and built the world's first working all-electronic television system, employing electronic scanning in both the pickup and display devices. U.S. Department of Education, Institute of Education Sciences. Dr. Carl Dietrich, PhD Thesis, the Massachusetts Institute of Technology, 2007, "Preliminary Results of Experimental Studies from Low Pressure Inertial Electrostatic Confinement Device" Journal of Fusion Energy, May 23, 2013, "Experimental Study of the Iranian Inertial Electrostatic Confinement Fusion Device as a Continuous Neutron Generator" V.

She could no longer be the partier she once was. Farnsworth recognized the limitations of the mechanical systems, and that an all-electronic scanning system could produce a superior image for transmission to a receiving device. [44], In May 1933, Philco severed its relationship with Farnsworth because, said Everson, "it [had] become apparent that Philo's aim at establishing a broad patent structure through research [was] not identical with the production program of Philco. Boys Basketball Open Gym. The 2022-23 Murray School Supply List is here! [49] That same year, while working with University of Pennsylvania biologists, Farnsworth developed a process to sterilize milk using radio waves. These losses can be at least five orders of magnitude higher than the energy released from the fusion reaction, even when the fusor is in star mode, which minimizes these reactions. ", "Philo T.

As a plasma consists of free-moving charges, it can be controlled using magnetic and electrical fields. The ease with which the ion energy can be increased appears to be particularly useful when "high temperature" fusion reactions are considered, such as proton-boron fusion, which has plentiful fuel, requires no radioactive tritium, and produces no neutrons in the primary reaction. The Farnsworths later moved into half of a duplex, with family friends the Gardners moving into the other side when it became vacant. Typical fusors cannot reach fluxes as high as nuclear reactor or particle accelerator sources, but are sufficient for many uses. We help build character for every student through our core values and active parent and community partners. You can add a copyright statement or legal disclaimer in this area if necessary. [32] Zworykin later abandoned research on the Image Dissector, which at the time required extremely bright illumination of its subjects, and turned his attention to what became the Iconoscope. 7, October 1967, P. T. Farnsworth (private communication, 1964), "On the Inertial Electrostatic Confinement of a Plasma" William Elmore, James Tuck and Ken Watson, The Physics of Fluids, January 30, 1959. [citation needed]. [22], There are numerous other loss mechanisms as well. Farnsworth won the suit; RCA appealed the decision in 1936 and lost. Learn more about Saint Paul Public Schools and how to apply. Thorson, R.D. What particularly interested Farnsworth about the device was its ability to focus electrons at a particular point. Web1 Percentages are based on full-time faculty whose race/ethnicity was known. [7] In September 1939, after a more than decade-long legal battle, RCA finally conceded to a multi-year licensing agreement concerning Farnsworth's 1927 patent for television totaling $1million. Hopes at the time were high that it could be quickly developed into a practical power source. [7][8] Fusors have also been developed commercially, as sources for neutrons by DaimlerChrysler Aerospace[9] and as a method for generating medical isotopes. Radiation is when energy leaves the cloud as light. J. Larmor, "On a dynamical theory of the electric and luminiferous medium", Philosophical Transactions of the Royal Society 190, (1897) pp. Santarius, G.L. [53] The inventor and wife were survived by two sons, Russell (then living in New York City), and Kent (then living in Fort Wayne, Indiana). Depression settled in and Lowder turned to the bottle as a source of escape. [citation needed], The FarnsworthHirsch fusor is an apparatus designed by Farnsworth to create nuclear fusion. [2] Hirsch published his design in a paper in 1967. [19] High enough in this case is such that the rate of the fusion reactions produces enough energy to offset energy losses to the environment and thus heat the surrounding fuel to the same temperatures and produce a self-sustaining reaction known as ignition. "[62] KID-TV, which later became KIDK-TV, was then located near the Rigby area where Farnsworth grew up. [citation needed], In a 1996 videotaped interview by the Academy of Television Arts & Sciences, Elma Farnsworth recounts Philo's change of heart about the value of television, after seeing how it showed man walking on the moon, in real time, to millions of viewers:[63], In 2010, the former Farnsworth factory in Fort Wayne, Indiana, was razed,[97] eliminating the "cave," where many of Farnsworth's inventions were first created, and where its radio and television receivers and transmitters, television tubes, and radio-phonographs were mass-produced under the Farnsworth, Capehart, and Panamuse trade names. [50], In 1967, Farnsworth and his family moved back to Utah to continue his fusion research at Brigham Young University, which presented him with an honorary doctorate. The banks called in all outstanding loans, repossession notices were placed on anything not previously sold, and the Internal Revenue Service put a lock on the laboratory door until delinquent taxes were paid. Box 37 Guilderland, NY 12085 Phone: 518-861-8591 Fax: 518-861-5874 Hours: 7:30 a.m. 2:28 p.m. My intuition would not be quieted. My spiritual walk with Jesus has played a huge role in my battle with depression and my faith also enables me to live free of depression, she said. It can also be called an electrostatic particle accelerator. The common sources of the high voltage are ZVS flyback HV sources and neon-sign transformers. First, there is the high-voltage involved. [17] However, in an earlier paper, "A general critique of inertial-electrostatic confinement fusion systems", Rider addresses the common IEC devices directly, including the fusor. Ion Flow and Fusion Reactivity, Characterization of a Spherically convergent ion Focus. [36] RCA later filed an interference suit against Farnsworth, claiming Zworykin's 1923 patent had priority over Farnsworth's design, despite the fact it could present no evidence that Zworykin had actually produced a functioning transmitter tube before 1931. By giving freely of their time, volunteers also send students the message that they matter. Electrostatic pressure from the positively charged electrodes would keep the fuel as a whole off the walls of the chamber, and impacts from new ions would keep the hottest plasma in the center. Farnsworth's television-related work, including an original TV tube he developed, are on display at the Farnsworth TV & Pioneer Museum in Rigby, Idaho. [20], Real electrodes are not infinitely thin, and the potential for scattering off the wires or even capture of the ions within the electrodes is a significant issue that causes high conduction losses. Durst, R.J. Fonck, A.C. Sontag, Nuclear Fusion, Vol. "[45] In Everson's view the decision was mutual and amicable. He thanks his family and those around him for helping him rise above depression. During the showcase, families are provided a brief introduction to the Highland Middle School community. The accelerated ions scatter with these and lose their energy, while ionizing the formerly cold atom. [7] In June of that year, Farnsworth joined the Philco company and moved to Philadelphia along with his wife and two children. [33] In a 1970s series of videotaped interviews, Zworykin recalled that, "Farnsworth was closer to this thing you're using now [i.e., a video camera] than anybody, because he used the cathode-ray tube for transmission. [35] Farnsworth's patent numbers 2,140,695 and 2,233,888 are for a "charge storage dissector" and "charge storage amplifier," respectively. The Philo T. Farnsworth Elementary School of the Jefferson Joint School District in Rigby, Idaho (later becoming a middle school) is named in his honor. Girls Basketball @ Farnsworth Middle School . To reach the required ~10keV, a voltage of 5kV is required, applied to both particles. Plasma clouds lose energy through conduction and radiation. There is no energy lost in this action, and in theory, assuming infinitely thin grid wires, the ions can circulate forever with no additional energy needed. This leads to a gas-like state of matter known as a plasma, consisting of free nuclei known as ions, and their former electrons. We will be fully enforcing our school board-approved Tardy Policy for. Window Rock High School, beginning October 11, 2022. Murray offers an inclusive environment to strengthen our students academic, social and emotional development. Various attempts have been made at increasing deuterium ionization rate, including heaters within "ion-guns", (similar to the "electron gun" which forms the basis for old-style television display tubes), as well as magnetron type devices, (which are the power sources for microwave ovens), which can enhance ion formation using high-voltage electromagnetic fields. The stress associated with this managerial ultimatum, however, caused Farnsworth to suffer a relapse. Kate Chapman, 44, used a variety of techniques to overcome her depression. Then create a plan to beat it and understand it may be a bit of struggle. In "Cliff Gardner", the October 19, 1999 second episode of, The eccentric broadcast engineer in the 1989 film, In "Levers, Beakmania, & Television", the November 14, 1992 season 1 episode of. These include academic institutions such as the University of WisconsinMadison,[5] the Massachusetts Institute of Technology[6] and government entities, such as the Atomic Energy Organization of Iran and the Turkish Atomic Energy Authority. [21][22] They agreed to fund his early television research with an initial $6,000 in backing,[23] and set up a laboratory in Los Angeles for Farnsworth to carry out his experiments. Today, I am a thankful woman.. Charged particles will radiate energy as light when they change velocity. WebFarnsworth Aerospace Lower. When atoms are heated to temperatures corresponding to thousands of degrees, the electrons become increasingly free of their nucleus.

Whereas 45 megakelvins is a very high temperature by any standard, the corresponding voltage is only 4 kV, a level commonly found in such devices as neon signs and CRT televisions. R.W. Bussard, "Method and apparatus for creating and controlling nuclear fusion reactions", Reducing the Barriers to Fusion Electric Power; G. L. Kulcinski and J. F. Santarius, October 1997 Presented at "Pathways to Fusion Power", submitted to. Fuel could then be injected through the wall, and once inside it would be unable to escape. I am honored to be serving the Murray community as the principal. It was only due to the urging of president Harold Geneen that the 1966 budget was accepted, extending ITT's fusion research for an additional year. WebWatch full episodes, specials and documentaries with National Geographic TV channel online. But, Farnsworth didn't have the mosaic [of discrete light elements], he didn't have storage. Gervase struggled with depression twice in her life both dealt with life and death. We believe in the picture-frame type of a picture, where the visual display will be just a screen. Discover our premier periodical database Gale Academic OneFile . WebFamilies are also invited to our showcase night on Thursday, January 12th, from 6:00 - 7:30 pm. In the original fusor design, several small particle accelerators, essentially TV tubes with the ends removed, inject ions at a relatively low voltage into a vacuum chamber. 205300 (Third and last in a series of papers with the same name), Inertial electrostatic confinement History, "A general critique of inertial-electrostatic confinement fusion systems", "13-year-old builds working nuclear fusion reactor", "How to Build a $1000 Fusion Reactor in Your Basement", "UWFDM-1267 Diagnostic Study of Steady State Advanced Fuel (D-D and D-3He) Fusion in an IEC Device", "Study for Ion Microchannels and IEC Grid Effects Using the SIMION Code", "D-3He Fusion in an Inertial Electrostatic Confinement Device", "Fundamental limitations on plasma fusion systems not in thermodynamic equilibrium", "Robert W.

Nevertheless, the fusor has since become a practical neutron source and is produced commercially for this role. Radiation increases as the temperature rises. D93 Live . One of the biggest problems in fusion research is to keep the hot fuel from hitting the walls of the container. [25] His backers had demanded to know when they would see dollars from the invention;[28] so the first image shown was, appropriately, a dollar sign. The charge would then accumulate in the center of the tube, leading to high amplification. For fusion to occur the ions must be at a temperature of at least 4keV (kiloelectronvolts), or about 45million kelvins. An important development was the successful commercial introduction of a fusor-based neutron generator. But as a wife and mother, I had so much to live for, Hardy said. The university also offered him office space and an underground concrete bunker for the project. Lenore Hirsch was 57 when she first felt depressed. Students can turn box tops in to their Foundationsteachers. Murray offers an inclusive environment to strengthen our students academic, social and emotional development. This Week in D93 News . Democrats hold an overall edge across the state's competitive districts; the outcomes could determine which party controls the US House of Representatives. To the extent that the ions remain at their initial energy, the energy can be tuned to take advantage of the peak of the reaction cross section or to avoid disadvantageous (for example neutron-producing) reactions that might occur at higher energies. This paper is not applicable to IEC fusion, as a quasineutral plasma cannot be contained by an electric field, which is a fundamental part of IEC fusion. She also told Deseret News National that yoga helped her overcome her struggles, too: Outside exercise is really the secret key to battling depression, as it gets endorphins pumping, which are needed, she said. To reach net power, fusion reactions have to occur fast enough to make up for energy losses. Many types of atoms can be fused. Kim Hardys depression started when she lost her business. Energy is lost with the particle. There was a time when Ingrid couldnt get out of bed. Fusors have at least two modes of operation (possibly more): star mode and halo mode. [26] Some image dissector cameras were used to broadcast the 1936 Olympic Games in Berlin. This would occur through simple Coulomb collisions in a matter of milliseconds, but beam-beam instabilities will occur orders of magnitude faster still. Importantly, the neutron generator easily sits on a benchtop, and can be turned off at the flick of a switch. [citation needed], Farnsworth remained in Salt Lake City and became acquainted with Leslie Gorrell and George Everson, a pair of San Francisco philanthropists who were then conducting a Salt Lake City Community Chest fund-raising campaign. How to Instructions on How to get Internet. [12] While attending college, he met Provo High School student Elma "Pem" Gardner[12] (19082006),[19] whom he eventually married. She died on April 27, 2006, at age 98. Lastly, she advises people to re-evaluate where they are in their own minds and how they think things are going in their life. But with the help of his roommate, and religion, he overcome his struggle with depression. John Lawson, "Some Criteria for a Power producing thermonuclear reactor", Atomic Energy Research Establishment, Hanvell, Berks, 2 November 1956. "One of those amazing facts of modern life that just don't seem possiblenamely, electrically scanned television that seems destined to reach your home next year, was largely given to the world by a nineteen-year-old boy from Utah Today, barely thirty years old he is setting the specialized world of science on its ears. The ease of doing a fusion reaction is measured by its cross section. [9] After the project was effectively ended, the former project manager established a company which is called NSD-Fusion. To begin with, the electrodes cannot influence the potential within themselves, so it would seem at first glance that the fusion plasma would be in more or less direct contact with the inner electrode, resulting in contamination of the plasma and destruction of the electrode. This could place an upper limit on the machine's power density, which may keep it too low for power production. Before leaving his old employer, Zworykin visited Farnsworth's laboratory, and was sufficiently impressed with the performance of the Image Dissector that he reportedly had his team at Westinghouse make several copies of the device for experimentation. To get net power from fusion, you must overcome these losses. Farnsworth was born August 19, 1906, the eldest of five children[11] of Lewis Edwin Farnsworth and Serena Amanda Bastian, a Latter-day Saint couple living in a small log cabin built by Lewis' father near Beaver, Utah. Fusors typically suffer from conduction losses due to the wire cage being in the path of the recirculating plasma. "Philo was a very deep persontough to engage in conversation, because he was always thinking about what he could do next", said Art Resler, an ITT photographer who documented Farnsworth's work in pictures. Any method which increases ion density (within limits which preserve ion mean-free path), or ion energy, can be expected to enhance the fusion yield, typically measured in the number of neutrons produced per second. MIDDLE SCHOOL. John Lindl, "Development of the indirect drive approach to inertial confinement fusion and the target physics basis for ignition and gain", Physics of Plasma, 1995. Thesis. We are proud of the many school activities that we provided our students. He returned to Provo and enrolled at Brigham Young University, but he was not allowed by the faculty to attend their advanced science classes based upon policy considerations. Nine GCSD employees honored at the districts 44th Employee Recognition Ceremony Oct. 28 update: turf field ribbon cutting; book donation; Trick or Treat Street; students selected to Area All-State Music Festival Farnsworth. The residence is recognized by an Indiana state historical marker and was listed on the National Register of Historic Places in 2013. John Lawson used this equation to estimate some conditions for net power[27] based on a Maxwellian cloud. She struggled to function after his surgery to remove the tumor and couldnt handle the problems associated with aiding her husband while also living in a small place: I found myself having fits of crying I couldn't stop, she said. However, Rider demonstrates that practical fusors operate in a range of modes that either lead to significant electron mixing and losses, or alternately lower power densities. Convergence, Electrostatic Potential, and Density Measurements in a Spherically Convergent Ion Focus, T. A. Thorson, R. D. Durst, R. J. Fonck, and L. P. Wainwright.
