针对位置敏感光电倍增管阳极信号的处理，设计并实现了一种新的前端电子电路，该电路可以抑制相邻通道之间的串扰。该电路在欧洲核子研究中心的测试光束中与一个闪烁光纤探测器一起进行了测试。与基于简单阈值鉴别器的传统电子学的基本性能进行了比较，如检测效率和均匀性，以及对单磁道的命中多重性。峰值检测电路的一个很大的优点是实验证明，特别是在其实时数字化的轨道位置没有显着的模糊性的轨道位置由于串扰。
In view of handling the anode signals from the position-sensitive photomultiplier a new front-end electronic circuit has been designed and realized, which allows one to suppress annoying effects of the cross-talk between adjacent channels. The circuit was tested in association with a scintillating fibre detector in a test beam at CERN. The basic performances, such as the detection efficiency and its uniformity, as well as the hit multiplicity for single tracks were compared to those of the conventional electronics based on the simple threshold discriminators. A great advantage of the peak-sensing circuit was experimentally demonstrated, in particular, in its real-time digitization of the track position without significant ambiguity of the track position due to the cross-talk.
