ATLAS μ子谱仪的刻度和性能

Calibration and Performance of the ATLAS Muon Spectrometer

E. Diehl

摘要:

ATLAS μ子谱仪设计用于测量μ子动量,分辨率为4%@100 GeV/c,上升到10%@1 TeV/c轨道动量。该谱仪由嵌入在由三个大型空心超导环产生的2 T磁场中的精确跟踪和触发室组成。精密探测器提供50微米的跟踪分辨率,伪快速度为2.7。该系统还包括一个光学监测系统,测量检测器的位置与40微米的精度。本文报道了ATLAS μ子谱仪的标定和性能。

英文摘要:

The ATLAS muon spectrometer is designed to measure muon momenta with a resolution of 4% @ 100 GeV/c rising to 10% @ 1 TeV/c track momentum. The spectrometer consists of precision tracking and trigger chambers embedded in a 2T magnetic field generated by three large air-core superconducting toroids. The precision detectors provide 50 micron tracking resolution to a pseudo-rapidity of 2.7. The system also includes an optical monitoring system which measures detector positions with 40 micron precision. This paper reports on the calibration and performance of the ATLAS muon spectrometer.
