| 摘 要： | 研究了软X射线能谱仪探测道系统(系统包括X射线二极管（XRD）、SUJ-50-10电缆和不同频带示波器)的响应时间。实验利用上海激光联合实验室的20TW激光器激光(激光能量约20J，脉冲宽度约1ps)打金箔靶产生的X光，用XRD探测系统测量，记录示波器有TK684C，TK694C和WM8500等。将实验数据进行了线性拟合和比对分析。滤片XRD探测系统的响应时间随偏压升高而加快，随传输电缆长度的增加而变慢，因此测量快信号过程时，应提高探测器偏压，缩短传输电缆，选择宽频带高采样率示波器，以便减少系统的响应时间，减小信号失真程度。

| Abstract: | The detection system consists of filter,XRD,SUJ-50-10 cable and different band oscillograph. 20TW laser facility of Shanghai Laser Unite Laboratory with energy about 20J,pulse width about 1ps was used, and Au foil target irradiated by laser pulse produced X-ray emission. Note oscillograph type have TK684C,TK694C and WM8500. The linear fit and comparision analysis of experiment data are proceeded. The response time of a filter-XRD detection system become fast along with based voltage, and become solw along with cable lenght. Therefor, when fast signal is measured, based voltage of detector must be increased, and cable length be shorten, and high band oscillograph be selected, in order to reduce system response time and decrease signal distortion. |
