摘要

束流位置探测器是最重要的束流测量部件之一，在北京正负电子对撞机二期（Beijing Electron Positron Collider Ⅱ，BEPCⅡ）的直线段、传输段和储存环上分布着包括纽扣型、条带型在内的多个束流位置探测器（Beam Position Monitor，BPM）。本文利用CST（Computer Simulation Technology）软件的微波工作室和粒子工作室对BEPCⅡ上的BPM相关参数进行了计算，其中包括BPM的信号强度、水平方向和垂直方向的灵敏度、纵向转移阻抗以及电极间的耦合参数等，比较了理论计算结果与实验测量结果之间的差别，计算了直线段条带型BPM的信号与频谱。这些工作是对现有BPM性质的深入了解，而相关计算方法对新机器如高能光源和环形正负电子对撞机上BPM的设计具有重要指导意义，为分析新建加速器的BPM相关问题提供了理论依据。

Abstract

Background

Beam position monitor (BPM) is one of the most important and most commonly used beam instruments. There are more than 150 kinds of BPM components in Beijing electron positron collider Ⅱ (BEPCⅡ) including the button-and stripline-types.

Purpose

This study aims to analyze the signal generated by the beam's electromagnetic field and calculate the transfer impedance and sensitivity map.

Methods

Microwave-and particle-studios of the computer simulation technology (CST) software were used to study the quality of the BPM. The simulation results such as the amplitude of button signal

the sensitivity of horizontal and vertical direction

transfer impedance

coupling coefficient of electrodes

etc

were compared with analytical formula. Further computation of signal for stripline BPM in time and frequency domain were also obtained.

Results

It showed that the calculation results accorded quite well with the experimental results.

Conclusion

CST is a useful tool to study the character of the BPMs and the simulation results can be used to optimize the geometry of the position monitor.
