摘要:

为了测量TWIST实验中TRIUMF低能表面μ子束流的位置和角度分布,研制了一个小质量时间膨胀室(TEC)。该实验是对μ子衰变的高精度测量,并且受到系统不确定性的影响,包括光束的稳定性,再现性和表征。由两个TEC模块测量的分布是TWIST精确模拟的重要组成部分。通过数据和模拟的比较提取的不确定性,必须是已知的,以评估潜在的TWIST结果的系统不确定性。TEC系统的设计标准,建设,调整,校准和操作进行了讨论,包括从初始光束研究的经验。还包括在TWIST模拟TEC数据的使用的简要说明。

英文摘要:

A low mass time expansion chamber (TEC) has been developed to measure distributions of position and angle of the TRIUMF low energy surface muon beam used for the TWIST experiment. The experiment is a high precision measurement of muon decay and is dominated by systematic uncertainties, including the stability, reproducibility, and characterization of the beam. The distributions measured by two TEC modules are one essential ingredient of an accurate simulation of TWIST. The uncertainties, which are extracted through comparisons of data and simulation, must be known to assess potential systematic uncertainties of the TWIST results. The design criteria, construction, alignment, calibration, and operation of the TEC system are discussed, including experiences from initial beam studies. A brief description of the use of TEC data in the TWIST simulation is also included.
