Abstract

ATLAS (A Toroidal LHC ApparatuS) is a general purpose experiment, which will start its operation at the Large Hadron Collider (LHC) at CERN in 2007. The ATLAS detector is designed to study the products of proton-proton collisions at c.m.s. energies of up to 14 TeV. Three Greek universities have taken the responsibility to construct 112 BIS-MDT (barrel inner small) chambers using 29000 drift tubes of ∼1.7 m length that have been quality tested before assembly. This paper describes the quality assurance and quality control (QA_QC) procedures for the monitored drift tubes (MDT), followed at the High Energy Physics Laboratory of the National Technical University of Athens. The quality parameters verification and the obtained results are presented.
