	Philo Farnsworth - Wikipedia, the free encyclopedia
		Farnsworth was born in Indian Springs, Utah on August 19, 1906.
		The cathode ray tube configuration developed from Farnsworth’s work was used in all television sets and other kinds of displays until the late 20th century when a small portion of televisions were made with alternate technologies such as liquid crystal displays.
		Farnsworth developed the Image Dissector, a practical all-electronic image scanning device that made it possible to dispense with the moving parts of mechanical television.

		Farnsworth reasoned that he could build an electrostatic confinement system in which the "wall" fields of the reactor were electrons or ions being held in place by the multipactor.
		The observers were startled, but the timing was bad; Hirsch himself had recently revealed the great progress being made by the Soviets using the tokamak, in the ensuing panic all available funding had been locked up by large research projects who resisted any funds being allocated to "new" systems, no matter how promising.
		In the Hirsch version of the fusor, the ions are produced by ionizing a dilute gas in the chamber.

	Farnsworth-Hirsch Fusor
		Farnsworth reasoned that he could build an electrostatic confinement system in which the "walls" of the reactor were electrons or ions being held in place by the multipactor.
		In the Hirsch version the basic mechanism consists of two concentric spherical grid electrodes in a vacuum chamber containing a very dilute fuel gas.
		Depending on the design, the inner electrode is negative and thus accelerates ions toward the center of the chamber, or alternately the inner electrode is positive and accelerates electrons towards the center.

	Science Fair Projects - Farnsworth-Hirsch Fusor
		Nevertheless the fusor has since become a practical neutron source, and is produced commercially for this role; it has been assembled in low-power forms by hobbyists.
		What particularly interested Farnsworth about the device was its ability to focus "electrons" at a particular point (for example, between nuclei).
		In the early days of controlled fusion experiments in the 1950s one of the biggest problems was to keep the heated fuel from hitting the walls of the container; if this were allowed to happen the fuel would rapidly cool off, leading to a huge loss of power.

		Philo Taylor Farnsworth (August 19 1906 – March 11 1971) was an American inventor.
		Patent battles and the outbreak of World War II meant that he was never able to profit from his invention and he remains a forgotten figure overshadowed by inventors such as John Logie Baird who invented an electromechanical version of TV in Britain.
		The cathode ray tube developed from Farnsworth's work was used in all television sets until the late 20th century and the advent of plasma screens and other variants.

		In electricity, a corona discharge is an electrical discharge brought on by the ionization of a fluid surrounding a conductor, which occurs when the potential gradient exceeds a certain value, in situations where sparking is not favoured.

		In the original fusor design, several small particle accelerators, essentially TV tubes with the ends cut off, inject ions at a relatively low voltage into a vaccum chamber.

	Philo Farnsworth
		Philo Taylor Farnsworth (August 19 1906 – March 11 1971) was an American inventor of the vacuum tube television display, an idea he conceived at age 14 and developed at age 21.
		Patent battles and the outbreak of World War II meant that he was never able to profit from his invention and he remains a forgotten figure overshadowed by inventors such as John Logie Baird who, unlike Farnsworth, did not invent a television system in use today.
		Farnsworth appears as a fictionalized character in Glen David Gold's novel Carter Beats the Devil (ISBN 0786886323).

		In 1926, Farnsworth formed a partnetship with George Everson in Salt Lake City to develop Farnsworth's television ideas.
		In 1929 the system was further improved by elimination of a motor generator; the television system now has no mechanical moving parts.
		Baird and Farnsworth competed with EMI for forming the standard television system for the U.K. By 1939 Farnsworth 's company had licenced patents to RCA.

	Electrostatic Fusion
		Here is a photo of Richard Hull's Fusor 2 in full "star mode", the mode that is most successful in making fusion.
		It was picked up by P. Farnsworth, one of the inventors of television, and head of ITT-Farnsworth Labs, in the 1950's, as a possible means of producing fusion.
		Work continued thru most of the 1960's, with significant contributions by Robert Hirsch, until ITT was unable to secure government funding and dropped it.

	Philo Farnsworth: Fusor (Inertial Electrostatic Confinement)
		In the mid-1950's, P. Farnsworth (one of the inventors of television) pondered the bright visible convergent focus glow that forms in the center of spherical multipactor tubes, and came up with the idea of using a spherical diode with the inner electrode in the form of a highly transparent wire grid (i.e.
		Hirsch (working at the ITT/Farnsworth Lab under Farnsworth's enthusiastic encouragement) used the IXL configuration, with the cathode (negative grid) in the center and the anode (positive) to the outside.
		While machines based on Farnsworth's Fusor are indeed easy to build, and worked better than any thermonuclear fusion machines until quite recently, it was immediately apparent to the researchers that they could never reach breakeven.

		The Fusor is a vaccum chamber device invented by Philo T. Farnsworth in the 1950's.
		An acceleration voltage (several kV) and the geometry of the electrodes cause so-called ion multipacting, and in this case concentration of accelerated ions in a small focus.

	IEC Tips - Tom Ligon (Site not responding. Last check: 2007-10-08)
		While it is possible to make a low-grade Fusor in a plastic vacuum dessicator chamber, I do not recommend it and three of the reasons are that it will not stop x-rays, may not stop UV, and also can't take heat, which the Fusor will produce.
		Heavy inert gases such as argon or xenon would make pretty glows in a Fusor, but be warned that they multiply ionize, and so multiply the acceleration of the grid: you might be using 10kV and getting 40 keV ions if the charge on each ion is +4, for example.
		While the original patents held by P. Farnsworth and Robert Hirsch, on which the Analog article were based, have long since expired, there are active patents in the field.

		What particularily interested Farnsworth about the device was its ability to focus electrons at a particular point.
		He demonstrated that all such systems will leak energy at a rapid rate due to Bremsstrahlung radiation, when electrons in the plasma hit other electrons or ions at a cooler temperature and suddenly decelerate.

		What we have here is a lack of independent confirmation on a new inertial confinement fusion apparatus that comes in a similarly compact package as the 1950s-vintage Farnsworth fusor.
