大亚湾实验RPC探测器信号读出前端板的高精度甄别阈的设计

Design of Threshold Setting Circuit with High Accuracy for DayaBay RPC Detector Readout Front-End Cards

介绍了大亚湾中微子振荡实验中阻性板探测器RPC(Resistive Plate Chamber)读出电子学前端板FEC(Front-End-Card)上高精度甄别阈电路的设计原理和相关测试。该电路具有高精度、低的甄别阈值设置能力、好的一致性保障等特点。在介绍该电路设计原理的同时,也给出了相应的检测实验和结果。

The Daya Bay RPC （Resistive Plate Chamber） readout FEC （front-end card） is responsible for collecting event data created by muons entering the detector systems. As required in the Daya Bay baseline, the FEC should have a threshold setting circuit with high accuracy and low threshold values. The design of threshold setting circuit on the FEC as well as tests to verify the design is introduced.
