  1. Update on LS1 Activities W.Baldini, N. Bondar, O.Maev,B. Schmidt LS1 Muon Meeting June-12th 2014

  2. Ongoing Activities • Grounding Improvement: DONE • Fixing problematic chambers in M2-5 (broken and noisy FEBs): ongoing, it will take ~3 weeks • Next week we plan to move to M1 back sides (A and possibly C) since there should be all the right conditions (nacelle available, CALO closed) • Starting from the beginning of July there will be the maintenance of the Marathon (replacement of the water-cooling connectors): • During the maintenance the corresponding detector side will be OFF • Right now we have problems with system configuration, probably due to ELMBs. Davide/Beat are investigating

  3. Ongoing Activities • Connectivity test (C side) stopped due to the ELMBs problem, hopefully it will be resumed soon… • HV: • Re-conditioning of M4R4 and problematic chambers: DONE • HV Connectors (RDB-racks end) improving: DONE • Check mapping of PNPI system for A-C side and re-connect the CMBs: Just started • Migration to CCPCs in progress, problem with USB-RS232 driver (WIN2008)

  4. Ongoing Activities • Next commissioning week: June 23-27, we will try to connect and turn on PNPI-HV-Chambers (at least one side), so far we left the chambers unplugged. • For more details, as usual you can refer to the e-logbook: http://lblogbook.cern.ch/MUON/
