| 摘 要： | 采用电荷分割方法设计了WSZ(Wedge-Strip and Zig)极紫外光探测器,其基于MCP的结构和单光子成像的特点使其在极弱光的探测方面具有独特的优势.设计了用于该探测器的快速三通道电荷放大电路和信号采集电路,以探测脉宽100～200 ms、总电荷量1～20 pC的电子脉冲.在真空条件下使用紫外光源对电路进行模拟试验,获得了峰值大小与阳极面板面积成比例的、噪音范围在10 mV以内的三路脉冲信号.模拟实验结果证明,该探测器预计分辨率有望达到100 μm×100 μm.

| Abstract: | 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. |
