基于GEM的中子束线监测器电子学系统研制

The Design of the Electronic System on Neutron Beam Monitor Based on GEM

简要介绍了一种基于GEM(Gas Electron Multiplier气体电子倍增器)的、用于对中子束进行实时监测的中子束线监测器GEM Monitor,重点介绍了其中电子学部分的设计,包括电路工作原理、系统结构、子板设计及Monitor母板FPGA逻辑及其算法的实现。最后给出了相关测试结果。

The Neutron Beam Monitor - a GEM based system used to monitor the neutron beams in real time - is introduced. The electronic parts are described in details, including the principles of the circuit, the system structure, the design of the Daughterboard and the logic and algorithm of the FPGA on the Monitor board. The test results are also given out in the final.
