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.
