Popis: This note summarizes the results of MDT ageing studies conducted at the CERN Gamma Irradiation Facility GIF between autumn 2001 and summer 2003, using for the first time a series-production MDT chamber (of type BIS) and a prototype of the gas recirculation system to be installed at Atlas. The main outcome of the measurements was a very high sensitivity towards any silicone contamination of the Atlas MDTs when operated in a high rate environment. The ageing effects observed were traced to several contaminated parts in the off-chamber gas system, proving the paramount importance of an effective quality control during the gas system assembly and component selection process.
