A Triple-Flash X-ray Generator Having Variable Spectra

抄録

An improvement of the triple-flash x-ray generator having variable spectra for biomedical radiography is described. This generator 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, a turbo molecular pump, and an x-ray to having cold cathodes. 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. The pulse widths were about 5Ons, and the minimum time interval between two pulses was about 100μs. The x-ray intensity was less than 1×10^-5C/kg at 1m 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.
