The Farnsworth/Hirsch fusor is a concentric spherical electrode accelerator which, with different included gases, different operating pressures, and various applied voltages and currents, can be used as a glow mode plasma sphere, a gas diode, an ion multipactor or even a means of producing neutrons.
