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%)-CO2(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.

Abstract
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%)-CO2(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.
