Composite electron beam vacuum tube

An electron beam vacuum tube assembly for a Febetron 705 electron accelerator, the electron beam vacuum tube assembly comprising:

• a composite insulator tube made of Rexolite® 1422;
• an anode assembly detachably connected to a first end of the composite insulator tube, wherein the anode assembly comprises an anode interface plate, a vacuum port assembly, and an exit window frame;
• and
• a cathode assembly detachably connected at a second opposite end of the composite insulator tube, wherein the composite insulator tube provides electrical isolation between the anode assembly and the cathode assembly.
