Abstract
The fundamental studies for the repetitive pulsed x-ray generator utilizing a hot cathode triode operated at high repetitive rates in the kllz-range are described. This generator consisted of the followingessential components: a constant high- voltage power supply, an energy storage condenser, a grid pulser, a DC-DC converter for supplying grid bias voltages, and an x-ray tube. The x-ray tube was of an enclosed-triode type and consisted of the following devices: an anode rod made of copper, a plane anode tip (target) made of tungsten, a grid made from tungsten wire, a focusing electrode made of iron, a hot-cathode (filament) made of tungsten, and a glass body. The condenser which was attached to the anode electrode was charged from 50 to 70kV, and the electric charges in the condenser were discharged repetitively by the grid electrode operated by the grid pulser. The pulse width was primarily determined by the pulse width from the grid pulser, the grid bias voltage, and the cut-off voltage for thermoelectrons, and could be controlled to about ips. The x-ray pulse height primarily increased according to increases in the charged voltage at a constant grid bias voltage. The x-ray intensity was 1. 35nC/kg at 0. 5m per pulse with a condenser charged voltage of 70kV, a grid bias voltage of -1. 0kV, and the charged voltage of the grid pulser of 400V.
