Abstract / Description:The resolution and e ciency of a precision drift-tube chamber for the ATLAS muon spectrometer with final read-out electronics was tested at the Gamma Irradiation Facility at CERN in a 100 GeV muon beam at photon irradiation rates of up to 990 Hz/cm2 which corresponds to twice the highest background rate expected in ATLAS. A silicon strip detector telescope served as external reference in the beam. The pulse-height measurement of the read-out electronics was used to perform time-slewing corrections which lead to an improvement of the average drift-tube resolution from 104 µm to 82 µm without irradiation and from 128 µm to 108 µm at the maximum expected rate. The measured drift-tube e ciency agrees with the expectation from the dead time of the read-out electronics up to the maximum expected rate.
