ATLAS桶形μ子谱仪的校准

Alignment of the ATLAS barrel muon spectrometer

F. Chevallier

摘要:

ATLAS实验的μ子光谱仪是有史以来最大的探测器之一。在大型强子对撞机上,新的物理符号可能会通过高动量μ子(1 TeV)出现。这种μ子的识别和精确的动量测量是ATLAS μ子谱仪的两个主要挑战。为了获得高能量μ子的良好分辨率(即,在1TeV下为10%),精密腔室的对准精度必须为50微米的量级。已经开发了几种程序来达到这样的精度。本文描述了用于对准μ介子子探测器的补充技术及其结果:光学系统、μ介子宇宙射线和碰撞产生的直线轨道。

英文摘要:

The muon spectrometer of the ATLAS experiment is one of the largest detectors ever built. At the LHC, new physics signs could appear through high momentun muons (1 TeV). Identification and precise momentum measurement of such muons are two of the main challenges of the ATLAS muon spectrometer. In order to get a good resolution for high energy muons (i.e. 10% at 1 TeV), the accuracy on the alignment of precision chambers must be of the order of 50 microns. Several procedures have been developed to reach such a precision. This document describes complementary techniques used to align the muon sub-detectors, and their results : the optical system, the muon cosmic rays and the straight tracks coming from collisions.
