BIL Chamber Tests in Roma Tre

The ATLAS group of INFN and Roma Tre University is responsible for the test and certification of 60 Barrel Inner Large MDT chambers for the ATLAS muon spectrometer. The gas distribution assembling techniques, the Quality Assurance and Quality Control (QA/QC) tests, the MDT read out and data acquisition at the cosmic ray stand and the standard analysis performed to certify the chambers performance are described. Our man power time estimate for each procedure is also reported. A section is dedicated to the procedures adopted to certify the chambers, together with a proposal for a “Chamber Certification Document” which should be used as a reference document for each assembled, equipped and tested chamber. Finally, a status report of the first 10% Roma Tre QA/QC test is provided.
