High power accelerator with three cathodes

A high power accelerator which can simultaneously produce three electron beams was developed. It is made up of primary energy storage system, spiral-strip transformer, pulse forming line using deionized water as insulation and diode with three cathodes. The three cathodes are stretched into three separate drift tubes, which can isolate the electromagnetic force between the produced electron beams. When a single cathode is connected to the diode, the accelerator can produce over 50 GW electric power; when three cathodes are connected to the diode, three electron beams each with over 10 GW electric power are produced. When the accelerator is used to drive three microwave tubes, three microwaves of 1.0 GW (L-band MILO), 1.0 GW(S-band MILO) and 300 MW(C-band VCO) can be obtained.
