AbstractIn 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.
Other Abstract为了研究储能电容初始电压、电极间距、充气压及灯管内径等条件对脉冲氙灯电流脉冲和发光脉冲的影响,在电极间距100~300 mm、充气压13.33~53.32 kPa、灯管内径6~12 mm、储能电容初始电压1.75~4.25 kV的条件下,分别测量了脉冲氙灯的电流脉冲和发光脉冲的变化状况。测量得到脉冲氙灯的电流脉冲宽度和发光脉冲宽度均在15~45 mus之间。对比发现:储能电容初始电压较高有助于获得高峰值、窄脉宽且滞后时间短的电流脉冲;具有较高充气压或较长电极间距的脉冲氙灯其电流脉冲与发光脉冲的峰值较小、脉
