摘要

本文研究了用于高能物理探测器的电子系统对共模杂散信号和外场的抗扰性。本研究基于MTL模型对屏蔽电缆进行数值模拟，分析光电探测器与敏感放大器连接中的共模和电磁辐射干扰。该装置与CMS中的甚前强子量热计(HF)相对应，它由约3000个光电倍增器和读出放大器组成，位于距离光电探测器约4米的地方。屏蔽线用于连接光电倍增管的阳极信号和放大器。这项研究允许在设计的早期阶段预测接地和屏蔽问题，并估计干扰噪声的影响。

Noise susceptibility analysis of the HF front-end electronics for the CMS high-energy experiment

This paper addresses the study of the immunity to common mode spurious signals and external fields of an electronic system used in high-energy physics detectors. This study uses numerical simulations based on a MTL model applied to shielded cables to analyze common mode and EM radiated interferences in the connection between photodetectors and sensitive amplifiers. This set-up corresponds to the Very Forward Hadron Calorimeter (HF) in CMS and it is composed by about 3000 photo-multipliers and read-out amplifiers located about 4 meters from the photodetectors. Shielded cables are used to connect the photomultiplier anode signals to the amplifiers. This study allows predicting grounding and shielding problems and estimating the effect of interference noise at early stages of the design.
