Abstract
In order to study the influence of the initial voltage, arc length, fill pressure and bore diameter of charging capacitor on current pulses and light pulses of the xenon flash lamps, at a pressure of 13.33~53.32kPa, the change of current pulses and light pulses were measured with the arc length of 100~300mm, the bore diameters of 6~12mm and the initial voltages in charging capacitor ranging from 1.75kV to 4.25kV. It was found that the pulse widths of light pulse and current pulse change from 15mus to 45mus. The result showed that with the higher voltage in charging capacitor, stronger peak current could be obtained, the width and delay of light pulses reduced. High fill pressure or long arc length can diminish the strength of peak light, expand the width of light pulses and extend the delay time. Although big bore diameter raises the peak current, it also expands the width of light pulses and diminishes the strength of peak light.
