A 400-keV X-ray generator with the pulse duration variable within 10-80 nsand an up to 70-Gy radiation dose

A high-power X-ray generator is created based on a universal setup for the experimental development of components of electrophysical installations (sp ark gaps, insulators, liquid resistors, etc.). The maximum energy of X-ray quanta is 400 keV, the pulse duration can be varied in steps from 10 to 80 ns, the radiation dose in the atmosphere near the exit window is similar to 70 Gy, and the X-ray pulse is synchronized within +/-15 ns with respect to the external trigger pulse. The key units of the setup are a shielded 600- kV Marx generator with a high-precision switching and a low-impedance high- voltage pulse former with a single or double coaxial line. The electric len gth of the lines can be increased by extending its body and conductors and by filling it with transformer oil, glycerin, or water. A design of the dio de with a similar to 70-kA radially converging ring electron beam and sidew all X-ray radiation release to the atmosphere through a thin dielectric win dow is presented. The dose characteristics and spectrum of the X-ray radiat ion are given.
