More Information
Summary:X-ray facilities based on a linear induction accelerator are designed to study of high density objects. It requires the high-current electron beam to obtain a small spot and bright X-ray source using a conversion target. The electrons source in such facilities is injectors capable generate pulses with a duration from tens of nanoseconds to several microseconds and a current of several kA. The transportation and focusing of high-current beams into diameter about 1 mm is difficult due to the space charge phenomena. 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 [1].
