吸管漂移室用于 CERN 通用介子和质子结构和光谱仪 (COMPASS) 的大面积跟踪 (LAT)。活动面积总计130平方米，覆盖12440根吸管，分为15个双层。该设计在空间分辨率、速率能力、低材料预算和探测器紧凑性方面进行了优化。讨论了腔室的机械和电气设计考虑因素以及新的生产技术。腔室的机械精度已使用 CCD X 射线扫描装置确定。描述了 COMPASS 中数据采集期间的性能结果。
Straw drift chambers are used for the Large Area Tracking (LAT) of the Common Muon and Proton Apparatus for Structure and Spectroscopy (COMPASS) at CERN. An active area of 130m2in total is covered by 12440 straw tubes, which are arranged in 15 double layers. The design has been optimized with respect to spatial resolution, rate capability, low material budget and compactness of the detectors. Mechanical and electrical design considerations of the chambers are discussed as well as new production techniques. The mechanical precision of the chambers has been determined using a CCD X-ray scanning apparatus. Results about the performance during data taking in COMPASS are described.
