Large-scale production of Monitored Drift Tube chambers for the ATLAS muon spectrometer

Precision drift tube chambers with a sense wire positioning accuracy of better than 20 mm are under construction for the ATLAS muon spectrometer. 70% of the 88 large chambers for the outermost layer of the central part of the spectrometer have been assembled. Measurements during chamber construction of the positions of the sense wires and of the sensors for the optical alignment monitoring system demonstrate that the requirements for the mechanical precision of the chambers are fulfilled.
