The Research of WSZ Extreme Ultraviolet Detector and the Data Acquisition Circuits
WSZ极紫外探测器及其信号采集电路的研究

WSZ (Wedge-Strip and Zig) extreme ultraviolet (EUV) detector was designed by the charge division theory.Based on MCP and single photon imaging,the detector has original advantages on faint light detection.Three channels data acquisition circuits were designed to detect pulses with 100~200 ms widths and 1~20 pC total charges.The circuits were tested under vacuum condition and electron pulses proportionate to the acreages of the anodes with noises less than 10 mV are gathered and processed.It is reasoned to expect a resolution of 100×100 of this detector.
