One of the first full scale prototypes of the Monitored Drift Tube(MDT) chambers for the ATLAS Muon Spectrometer was built in 1998 at the Max Planck Institute in Munich in collaboration with the LMU Munich and Freiburg University and was placed in a muon testbeam at CERN. The tests necessary to verify if the chamber’s performance fullfills the high requirements needed in the demanding ATLAS environment, were continued also last summer. This time the chamber was filled with the ATLAS baseline gas ArCO2(93:7). A method for determining the wire positions of the chamber using no external reference system, which was proved succesful for a small group of 12 tubes of the chamber last year, was tested again with the new data and was extended to a bigger area of the chamber. The results were finally compared with these of the X-Ray Tomograph at CERN.
