Abstract
The high-rate performance of a multiwire proportional chamber of the LHCb muon detector was tested. The chamber, equipped with the final front-end electronics, was tested using a similar to 100GeV muon beam superimposed on a 662 keV gamma flux of variable intensity produced by the Cs-137 radioactive source of the CERN Gamma Irradiation Facility (GIF). No significant variation in the muon detection efficiency or in the time response of the chamber was observed at the highest gamma rate. (C) 2008 Elsevier B.V.
