X-ray tube with a photocathode

The design and technology of a X-ray tube with the photocathode are developed. Use of the photocathode and dynode system allows, unlike all other known types of electron emitters, essentially to improve characteristics of a X-ray tube: to facilitate management of current and intensity of the generated X-ray radiation, to provide exact synchronization of the beginning of generation of radiation at X-ray researches of dynamic processes.
