摘要:

大型强子对撞机(LHC)ATLAS探测器的μ子谱仪的平行漂移管(MDT)室由3-4层加压漂移管组成,位于承载光学变形监测系统的空间框架的两侧。该室必须提供一个轨道位置分辨率为40微米,单管分辨率至少为80微米,传感线定位精度为20?微米(rms)。最大的MDT室之一,432漂移管的3.8米长的全尺寸原型的可行性进行了论证。对于ATLAS μ子谱仪,必须建造88个这种类型的腔室。第一个腔室已经完成,导线定位精度为14微米(rms)。

英文摘要:

The Monitored Drift Tube (MDT) chambers for the muon spectrometer of the ATLAS detector at the Large Hadron Collider (LHC) consist of 3-4 layers of pressurised drift tubes on either side of a space frame carrying an optical deformation monitoring system. The chambers have to provide a track position resolution of 40 microns with a single-tube resolution of at least 80 microns and a sense wire positioning accu- racy of 20 ?microns (rms). The feasibility was demonstrated with the full-scale prototype of one of the largest MDT chambers with 432 drift tubes of 3.8 m length. For the ATLAS muon spectrometer, 88 chambers of this type have to be built. The first chamber has been completed with a wire positioning accuracy of 14 microns (rms).
