Annotation: Developed in the project of electron beam gun with thermionic cathode is presented. The main gun components mounted on standard ceramic insulators. The cathode assembly is easily removable, which does not require adjustment when replacing. The presence of a removable cathode unit allows the operation using cathodes of direct and indirect heating. The maximum power in the beam is 15 kW and 60 kW at an accelerating voltage of 60 kV, while the device with the cathode of direct and indirect heating, respectively.
