Detector activities 1/3 DetectorIntervention TPCGeneral consolidation work Adjust gas flow through CO2 volumes Install Ethernet switch redundant system Route cables GEM proto TPC laserInvestigate problem with with Laser_1 and RS232 communication with Laser_2. TRDInstallation of multiplexers and additional switches for the TRD Ethernet connectivity. Check of the LV connections on the C side of the TRD supermodules (IR camera, voltage measurements). Tightening of problematic LV connections. Adding of patch cables for problematic connections. Backup trigger fibers to TRD sector 02 and 03 seem to be broken. Spare fibers will be pulled from pretrigger (bottom of L3) to the C-side of sector 02/03. Check of the TRD gas pipes in the cavern and of the gas connections at the TRD supermodules 14/9/12TS preparatory meeting - A.Tauro3

DCS Main activities / perturbations: Monday PM – Database maintenance (transparent) Tuesday – 09h00: network intervention by IT on router serving devices in cavern, side C 30 min ‘blackout’ in worst case, users have been warned with details of intervention by mail – Standard maintenance of DCS cluster, might need reboot of cluster – Maintenance central systems (backups etc.) - several short interruptions, might have impact on central running – Shut down machines in old cluster that are not required for operation Change/repair a few PCs; some tuning of PVSS projects - will be coordinated directly with the experts concerned. Detectors will receive instructions for cleanup and backup of their projects Propose, as usual, full functional test with all detectors on Friday (supersafe- safe-ready-safe-supersafe cycle). 14/9/12TS preparatory meeting - A.Tauro9 Andre
