Descripción
Sumario:The first Barrel Inner Large chamber of the Monitored Drift Tube (MDT) tracking detector for the muon spectrometer of the ATLAS experiment has been tested with a high-energy muon beam. After a description of the MDT characteristics, we present the test beam experimental set-up, the data analysis techniques and discuss the results. The chamber was operated with a Ar(93%)-CO/sub 2/(7%) gas mixture at 3-bar pressure. The performance studies include the chamber calibration, the single-tube resolution, efficiency and electronic noise, and their behaviour as a function of the high- voltage setting and discriminator threshold.
