Paper Abstract

The construction and the fundamental studies for a pulsed x-ray and charged particle beam generator used in the low photon energy region are described. This generator consisted of the following components: a high-voltage power supply, a high-voltage coaxial oil condenser of 120kV-0.2pF, a gas gap switch, a low-impedance coaxial transmission line, a turbo molecular pump, and a pulsed x-ray and charged particle beam tube. The condenser was charged from -60 to -100kV and was connected to the radiation tube through a gas gap switch. The electric charge stored by the condenser was discharged to the radiation tube when the gas gap switch was closed. This radiation tube produced pulsed (flash) x-rays through copper foil anodes. The charged particle beam was produced by the ionized air outside of the anode window due to the production of a high dose rate of x-rays, and these charged particles were accelerated by the electric field between the anode and ground. Both kinds of radiation were produced simultaneously, and the migration time of the charged particles corresponded to the duration of the pulsed x-rays.
