Abstract
The construction and the fundamental studies of a kilohertz-range flash x-ray generator utilizing a hot-cathode triode for high-speed radiography are described. This generator consisted of the following components: a constant high-voltage power supply, an energy- storage main condenser of 97 nF, a grid pulser, and an x-ray tube. The x-ray tube was of an enclosed-triode type and was composed of the following major parts: an anode rod made of copper, a plane anode tip (target) made of tungsten, a focusing electrode made of iron, a hot cathode (filament) made from a tungsten wire, a tungsten grid, and a glass tube body. The main condenser was charged from 50 to 70 kV, and the electric charges in the condenser were discharged repetitively by the grid pulser. The temperature of the cathode was about 2,000 K, and the cathode current was primarily controlled by the grid voltage at a constant filament temperature. The pulse width was less than 2 microsecond(s) , and the maximum repetition rate was about 30 kHz. The x-ray intensity was 67.3 nC/kg at 0.5 m per pulse with a peak grid voltage of 1.2 kV and a charged voltage of main condenser of 70 kV.
