CMS μ子系统使用2008年收集的宇宙射线μ子和2008年大型强子对撞机循环光束测试的束晕μ子进行校准。对准后，同一筒腔内超层相对位置的最敏感坐标分辨率为80微米，同一环形结构中端腔相对位置的最敏感坐标分辨率为270微米。中央枪管腔相对于跟踪器位置的分辨率由两个极端估计组成，200和700微米，由两个互补的研究提供。只要稍加修改，校准程序就可以使用LHC碰撞产生的μ子，从而带来额外的重大改进。*见附录A的合作成员名单[X iv: 91]。[40] 22 v2 [ph ys . ic . in side t] 8 F b 2 01 0 FERMILAB-PUB-10-163-CMS
The CMS muon system has been aligned using cosmic-ray muons collected in 2008 and beam-halo muons from the 2008 LHC circulating beam tests. After alignment, the resolution of the most sensitive coordinate is 80 microns for the relative positions of superlayers in the same barrel chamber and 270 microns for the relative positions of endcap chambers in the same ring structure. The resolution on the position of the central barrel chambers relative to the tracker is comprised between two extreme estimates, 200 and 700 microns, provided by two complementary studies. With minor modifications, the alignment procedures can be applied using muons from LHC collisions, leading to additional significant improvements. ∗See Appendix A for the list of collaboration members ar X iv :0 91 1. 40 22 v2 [ ph ys ic s. in sde t] 8 F eb 2 01 0 FERMILAB-PUB-10-163-CMS
