为暗物质粒子探测器（DAMPE）的BGO电磁量能器（ECAL）研制了一种多倍增极读出光电倍增管（PMT）基板。为了覆盖能量测量的高动态范围，从不同的敏感倍增器电极2、5和8（Dy 2、Dy 5和Dy 8）读出信号。利用发光二极管（LED）系统和宇宙射线对这种新型基板的性能进行了研究。使用VA32读出专用集成电路（ASIC）可以实现0.5到1.0× 105MIP的宽测量范围。
A base board for photomultiplier tube (PMT) with multi-dynode readout has been developed for the BGO electromagnetic calorimeter (ECAL) of the Dark Matter Particle Explorer (DAMPE). In order to cover a high dynamic range of energy measurements, the signals are read out from different sensitive dynodes 2, 5, and 8 (Dy2, Dy5 and Dy8). The performance of this new type of base board is studied with a light-emitting diode (LED) system and cosmic rays. A wide measuring range from 0.5 to 1.0×105MIPs can be achieved using the VA32 readout Application Specific Integrated Circuit (ASIC).
