提出了一种新颖的微通道板读出方案--十字形阳极。交叉条阳极具有粗（0.5 mm）多层金属和陶瓷交叉条图案，其通过直接感测每个条上的电荷并随后确定每个事件的电荷云质心来编码事件位置。事件位置编码是通过阳极上的芯片级前置放大器、随后的单个剥离电荷值的模数转换和软件质心确定来完成的。我们发现，空间分辨率（
We have developed a novel microchannel plate readout scheme, the cross strip anode. The cross strip anode has a coarse (0.5 mm) multilayer metal and ceramic cross strip pattern that encodes event positions by direct sensing of the charge on each strip and subsequent determination of the charge cloud centroid for each event. Event position encoding is accomplished with chip level preamplifiers on the anode, subsequent analog-to-digital conversion of individual strip charge values, and a software centroid determination. We find that the spatial resolution (
