Paper Abstract

The fundamental studies for a repetitional (triple exposure) pulsed x-ray generator having variable spectra for biomedical imaging are described. This generator consisted of the following components: a high voltage generating unit, a voltage divider unit, three high voltage pulsers with output voltages ranging from 50 to 200kV, a triple parallel type of high speed impulse switching system, a high power gas diode having three terminals, and two types of evacuated x-ray tubes, each of a different type. The pulse condensers of the pulsers were charged to the same or different energies by using a voltage divider unit and were connected to the single x-ray tube through a high power gas diode. The duration of each x-ray pulse was about 1ps, and the minimum time interval between two pulses was about 100ps. The maximum intensity was about 10C/kg at lm/pulse, and the effective focal spot size varied from 0.2 to 3.0mm in diameter. The triple exposure of pulsed x-rays having variable spectra and time intervals was obtained by controlling the condenser charging voltage, the tube impedance, the diode impedance, and others.
