MICE μ子束中性粒子污染测量

Measurement of Neutral Particle Contamination in the MICE Muon Beam

Rob Roy Fletcher, Linda Coney, Gail Hanson

摘要:

μ子电离冷却实验(MICE)正在卢瑟福阿普尔顿实验室(RAL)的ISIS质子同步加速器上进行,以测量μ子束的电离冷却。在最近的数据采集过程中,确定MICE μ子束中存在显著的中性粒子背景污染。这种污染会在MICE中产生不必要的触发器,从而降低运行期间获取的有用数据的百分比。本文介绍了使用飞行时间探测器进行的分析,用于测量和识别正负μ子束中的污染源。

英文摘要:

The Muon Ionization Cooling Experiment (MICE) is being built at the ISIS proton synchrotron at Rutherford Appleton Laboratory (RAL) to measure ionization cooling of a muon beam. During recent data-taking, it was determined that there is a significant background contamination of neutral particles populating the MICE muon beam. This contamination creates unwanted triggers in MICE, thus reducing the percentage of useful data taken during running. This paper describes the analysis done with time-of-flight detectors, used to measure and identify the source of the contamination in both positive and negative muon beams.
