无创单束团匹配和发射度监测器

Non-invasive single-bunch matching and emittance monitor

Andreas Jansson

摘要:

在线监测高亮度光束的光束质量只能使用非侵入性仪器。对于匹配测量,很少有这样的仪器可用。一个候选人是一个四极皮卡。为此,我们研制了一种新型的四极拾波器,并在CERN的26 GeV质子同步加速器上安装了一套由两个四极拾波器组成的测量系统。使用这些拾取器的信息,可以分别确定每个聚束在水平和垂直平面中的注入匹配和发射度。本文介绍了测量方法和第一年使用的一些结果,以及与其他测量方法的比较。

英文摘要:

On-line monitoring of beam quality for high brightness beams is only possible using non-invasive instruments. For matching measurements, very few such instruments are available. One candidate is a quadrupole pick-up. Therefore, a new type of quadrupole pick-up has been developed for the 26 GeV Proton Synchrotron (PS) at CERN, and a measurement system consisting of two such pick-ups is now installed in this accelerator. Using the information from these pick-ups, it is possible to determine both injection matching and emittance in the horizontal and vertical planes, for each bunch separately. This paper presents the measurement method and some of the results from the first year of use, as well as comparisons with other measurement methods.
