  1. MDT Activities for 2012-2014 Long LHC Shutdown

  2. Pre-Commissioning, Pit Installation and Commissioning • EE side A (Tiesheng …) • sMDTs to fill MDT holes (elevator region) (MPI …) • DCS integrations for EE side A and sMDT chambers • MROD for sMDT chambers ??? • Alignment (Installation and Commissioning) • EE side A alignment (Christoph …) • BEE alignment (Christoph …) • Barrel and Endcap in BIS7/8 region ??? • Repair and improve Barrel Optical alignment ??? • Small Wheel C (US Muon Group …), Repair and Commissioning on ground, and re-commissioning at pit, detail plan to be discussed and decided.

  3. Gas • EE side A (Joerg …) • sMDTs to fill MDT holes (Joerg …) • EO gas leak fix (systematic replacing gas jump of leak area under HV or signal hedgehog cards + checking) (Anotoli …) • Replace Zeolith Gas filter if necessary (i.e., depending on analysis results) (Freiburg …) • Resolve gas leak puzzle of large difference between measured total gas leak and total MDT chamber gas leak??? • DAQ • Replace DAQ computers (ROS) (TDAQ + Enrico …) • Replace MDT standalone DAQ computers (Enrico …) • DCS, replace CAN and computers (detail see Stephanie’s talk) • UM Gas Monitor (Dan …), replace computers (Window and Linux) and update software. • MDT maintenance and repair
