Response time measurement for a filter-X-ray diode detection system

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 inreased, and cable length be shorten, and high band oscillograph be selected, in order to reduce system response time and decrease signal distortion．
