| 中文摘要: |
| 针对交叉条形(XS)阳极探测器所存在的 解码误差问题,分析了XS阳极解码误差产生的原因及变化规律,得到了微通道板 (MCP)出射电子云的直径需要覆盖XS阳极约1.64个周期的最佳工作条 件。根据 分析结果设计制备了一种周期为635μm的XS阳极结构,并对该阳极 的电荷输 出信号波形进行了采样。在分析了输出信号波形的线性及噪声的基础上,估算 出XS阳极探测器的最大计数率和空间分辨率分别为1MHz和4μm。 |

| Aiming at these existing problems on decoding error in the XS detector,the causes of decoding error and its changing rules have been analy zed in this paper.These results show that MCP exiting electron cloud diame ter must cover about 1.64XS anode periods in order to obtain the best spatial resol ution. An XS anode with a period of 635μm has been designed and fabricated according to above-mentioned analytic results,and sampling of the anode output signal wavef orms is also finished.The maximum count rate of 1MHz and the spatial resolution of 4μm can be estimated in the light of XS anode output waveform linearity an d noise. |
