摘要：CMS探测器的μ子光谱仪对准系统由光学和模拟位置传感器三个独立的子系统组成。它使介子室相对于彼此和中央硅跟踪器对齐。2008年，在一个扩展的宇宙射线运行期间，系统开始在全磁场下调试。该系统成功地跟踪了介子探测器在磁力作用下高达18毫米的运动和几亿弧度的旋转。根据坐标和子系统的不同，系统实现了140 ~ 350µm和30 ~ 200µrad的腔室对准精度，接近实验精度要求。根据与独立摄影测量的比较，绝对位置的系统误差估计为340-590µm。
A BSTRACT : The alignment system for the muon spectrometer of the CMS detector comprises three independent subsystems of optical and analog position sensors. It aligns muon chambers with respect to each other and to the central silicon tracker. System commissioning at full magnetic field began in 2008 during an extended cosmic ray run. The system succeeded in tracking muon detector movements of up to 18 mm and rotations of several milliradians under magnetic forces. Depending on coordinate and subsystem, the system achieved chamber alignment precisions of 140–350 µ m and 30–200 µ rad, close to the precision requirements of the experiment. Systematic errors on absolute positions are estimated to be 340–590 µ m based on comparisons with independent photogrammetry measurements.
