Abstract
In a high power hot cathode electron beam gun with a cathode and cathode heater which are caused to float at high potential, a high voltage cable termination is provided with built-in transformer. The transformer is characterized as having an input impedance matched to the cable and output impedance matched to the cathode heater. Using this configuration, the cathode power supplies and cathode/heater control assembly can be located in remote locations.
Claims4
In a high power hot cathode electron beam gun wherein said cathode and cathode heater are caused to float at high potential, the improvement comprising providing a high voltage cable termination with built in transformer, said transformer having an input impedance matched to said cable and an output impedance matched to said cathode heater.
In a high power hot cathode electron beam gun assembly comprising a cathode heater and high voltage power supply, electron beam control elements, high voltage isolation transformer to power a cathode heater and current matching transformer, the improvement comprising housing said electron beam control elements, isolation transformer and high voltage power supply in an enclosure located remotely from said hot cathode and cathode heater wherein said enclosure is functionally connected to said hot cathode and cathode heater by means of a high voltage cable having a high voltage termination with built in transformer, said transformer being located proximate said hot cathode and having an input impedance matched to said cable and an output impedance matched to said cathode heater.
