摘要

电子储存环中损失的束流电子

在撞击真空室壁时

引起“电子 -γ -电子”簇射

在撞击点的下游

真空室的外表面形成次级电子（shower电子）的分布。通过探测这些shower电子

可以知道上游某处的束流损失状况。“合肥国家同步辐射实验室加速器二期工程”中的电子储存环束流损失监测系统

就是利用了这个原理。在分析了原有加速器束流损失监测系统的缺陷并对国际上各大型加速器进行了调研的基础上

对该系统中的探测器选型、探测器安装位置的选择以及系统的整体结构等物理问题作了阐述

Abstract

The electrons lost from the storage ring beam produce a shower of particles when striking the vacuum chamber

and the beam losses can be probed by detecting the shower electrons distributed on the surface of beam pipe. Based on this principle

a new Beam Loss Monitoring System (BLM System) was designed and installed during the upgrading of accelerator in NSRL. In this paper

the selection of BLM detectors

the position to install them

and also the structure of BLM system were discussed in detail.
