Studies on Ageing and Reanimation of Drift Tubes for the ATLAS Muon Spectrometer

The drift tubes of the ATLAS muon spectrometer are expected to accumulate charges of <br>up to 0.6 C/cm wire during ten years of operation. Five drift gases were developed for <br>the drift tubes and tested in various ageing setups. The influence of the drift gas on <br>the ageing performance was studied. Also the gas flow, additives to the drift gas, cathode <br>coating, cathode cleanliness, irradiation rate and high voltage were varied to determine <br>their influence on the ageing performance. <br>Furthermore, a technique for reanimation of inefficient drift tubes was developed, which <br>enables safe reanimation of drift tubes with minimal effort. This technique is also suitable <br>for cathode cleaning and noise curing.
