Paper Abstract

The fundamental studies for the triple-flash x-ray generator having variable spectra for biomedical radiography are described. Two types of triple-flash x-ray generators consisted of the following components: a high-voltage generating unit, a voltage divider unit, three high-voltage pulsers, a triple-parallel impulse switching system utilizing air gap pulsers for the main gas gaps, a high-power gas diode having three terminals, a turbo molecular pump, and three x-ray tubes having cold cathodes. For the single-tube generator, 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 x-ray tube through a high-power gas diode. In contrast, the pulsers were connected directly to three tubes without a diode. The duration of each x-ray pulse was a few ps, and the minimum time interval between two pulses was about 100ps (single-tube type), the x-ray intensity was less than lx10-5C/kg at lm per pulse, and the effective focal spot size was determined by the diameter of the anode rod. The triple exposure of pulsed x-rays having variable spectra and time intervals was obtained.
