摘要：

The Monitored drift tube (MDT) chambers for the union spectrometer of the ATLAS detector at the large hadron collider (LHC) consist of three or four layers of pressurised drift tub es on either side of a space frame carrying an optical deformation monitoring system. The chambers have to provide a track position resolution of 40 mum with a single-tube resolution of at least 80 mum and a sense wire positioning accuracy of 20 mum (rms). The feasibility was demonstrated with the full-scale prototype of one of the largest MDT chambers with 432 drift tubes of 3.8 in length. For the ATLAS union spectrometer, 88 chambers of this type have to be built. The first chamber has been completed with a mire positioning accuracy of 14 mum (rms).
