Abstract

A method for profile measurements of small transverse size beams by means of a vibrating wire is proposed. The main idea is to use the vibrating wire motion during its oscillations as a scanning mechanism and synchronously measure the scattered/reflected particles/photons created through the interactions of the measured beam with the wire. The method is expected to be applicable for thin beams in particle accelerators. The proof-of-principle test results, obtained using a laser beam, are presented.

摘要

提出了一种利用振弦对小横向尺寸束流进行轮廓测量的方法。主要思想是将振弦振荡过程中的运动用作扫描机制，并同步测量被测束流与弦相互作用产生的散射/反射粒子/光子。该方法有望应用于粒子加速器中的细束流。给出了使用激光束获得的原理验证测试结果。
