UoA, NTUA, AUThATLAS Overview week 1-7 Oct 2004 BIS Integration and Commissioning Status All 112 bare BIS chambers are at CERN All but 5 are equipped with gas bars, FC’s and HH cards 78 chambers (156 ML’s) have been leak tested 29 chambers are kept pressurized at 3bars, to be measured periodically. They will be certified at the 283 leak test set up 3 chambers are fully equipped with cables sensors and electronics 1 chamber was measured in the cosmic stand

UoA, NTUA, AUThATLAS Overview week 1-7 Oct BIS Chambers have been leak tested 156 ML’s pass the leak test 4 ML’s have a pressure drop > 4mbars/day

UoA, NTUA, AUThATLAS Overview week 1-7 Oct BIS chambers has been equipped with mezzanine cards, RO cables, T-sensors and alignment cables Open issues -Missing items Define the procedure to fix the stiff RO cables in order to respect the chamber envelope Some of the CCC platform placement tools Protective covers and their fixing procedure

UoA, NTUA, AUThATLAS Overview week 1-7 Oct 2004 A BIS chamber -12 mezzanines (36 tube/layer)- is measured at the cosmic stand at Bldg 283 Maximum Drift Time variation for the 12 mezzanines < 20μsec (mezz for the trigger is used)

UoA, NTUA, AUThATLAS Overview week 1-7 Oct 2004 Summary for BIS integration BIS chamber integration proceeds without major problems and delays The main effort is now concentrated in the logistics of chamber handling for cabling Cosmic test has taken off. Online monitoring is now running on root. Improvements are envisaged
