X-ray complexes based on a linear induction accelerator are designed to study of high density objects. It requires of high-current electron beam to obtain a small spot and bright x-ray source using a conversion target. The electrons source in such installations is injectors capable generate pulses with a duration from tens of nanoseconds to several microseconds and a current of several kiloamperes. The transportation and focusing such beams into diameter about 1 mm is difficult due to of the space charge effect. In similar induction accelerators (DARHT, AIRIX, FXR, etc.), auto-emission cathodes are used to obtain high-current electron beams. The use of a thermionic cathode, in compared to auto-emission cathode, provides stable generation of several pulses with a time interval of several microseconds, but makes high requirements on the injector vacuum system: not less than 10-7 Torr.
