FIELD: electrical engineering.
SUBSTANCE: this device comprises gas discharge chamber composed of two spherical metal electrodes separated by insulator, pulse current generator composed of capacitor bank with HV initiation switch and working gas generator with electric power supply. Besides, it incorporates shunting switch arranged at rear part of electrodes outside the chamber. It is composed of cylindrical discharger with HV electrode and case with spark firing sources arranged thereat. Said switch can be composed of industrial HV semiconductor commutators.
EFFECT: minimised ingress of impurities into discharge chamber, longer life and higher yield of penetrating rays.
