Abstract
A super-power, high voltage klystron includes an output cavity operating in the TM.sub.01x mode, where x is greater than zero.
Claims31
A super-power, high voltage klystron tube comprising an electron gun for emitting an electron beam, an input cavity coupled to the beam, a drift region downstream of the input cavity through which the beam travels, an output cavity downstream of the drift region coupled to the beam, intermediate resonant cavity means between the input and output cavities, a collector for the electron beam downstream of the output cavity, the output cavity being configured relative to the frequency of oscillations induced in the beam so the cavity operates in the TM.sub.01x mode, where x is greater zero.
