Installation and Commissioning Planning Leslie Camilleri Calorimeter Commissioning Meeting 5 th September 2006

Overall Planning  Overall infrastructure  Installation C-side: Priority.  Installation A-side  Commissioning before beams  Commissioning with beams 2007 and … Many tasks have no date or length attached to them. In particular A-side installation. We will learn more about duration of VFE-FE cabling tasks with PS Top cabling. Links have to be established carefully.

Specific issues PS/SPD  PS needs 25 more trigger cables installed on detector. Access.  PS and SPD need light tightening with Kevlar/Al foils(?). Access. During SPD/PS cooling work?  Request to check light tightness before VFE installation.  PS/SPD cable tray material not long enough. Welding? Delay?  Before VFE-FE cabling: Lower SPD/Guidance, alignment, cooling, RICH 2 platform for cable reel storage.  Is presence of racks on ECAL platform compatible with VFE-FE cabling? Yes, maybe move ECAL from time to time.  LED control drivers under development. Start manufacturing: January  Need to design and build mechanical support for radioactive source spectrometer for checking SPD/PRS in situ.  Detector access for cooling installation?  Cooling circuits and distribution from Main to detector: Who? When? How long? Manifold location?

PS/SPD cabling sequence  Sequence: C-side PS TOP, PS BOT, SPD TOP, SPD BOT, then A-side  Receive cable tray material: end of September.  Assemble into required lengths.  Connect to distribution cooling pipes before( or during) installation.  Install fixture (“potence”) for supporting PS cable chain.  Install water retaining trough and racks on ECAL platform.  Install ECAL gallery.  PS cooling installation requires: PS closed, and ECAL and (maybe) HCAL open. for access to PS.  If HCAL needs to be moved, this operation must wait end of ECAL cable (PMT end) repairs.  Install “passerelle” between two ECAL arrays for access to PS. (Muon group design). Approval by safety. Also ladders or scaffolding for bottom boxes.  Install cooling inside SM boxes.  Install distribution to these boxes along TOP and BOT, maybe already connected to cable trays or after cable tray installation.  Install lateral distribution TOP to BOT connecting pipe.  Test for leaks with gas system.  SPD cooling installation requires: SPD open, and PS, ECAL closed. Cooling installation: 1 week per half detector after infrastructure in place.

 RICH2 platform installation.  Cable reels must be ready by then.  Chariot and rails for PS cable chain installed.  Pull cables from TOP PS to storage 1 on RICH platform.  Install Cable chain for PS.  TOP PS cables through cable chain to storage 2.  BOT PS cables to storage 1.  Then, through cable chain to storage 2.  Move cable chain.  Storage 2 to ECAL platform.  Repeat for SPD.

Specific ECAL/HCAL issues  ADC cables repairs finished ~end of September/beg. October.  ECAL PMT end repairs CRYO side finished end of September. Extra person as of mid-September. A-side?  HCAL radioactive source safety approval and commissioning.  HCAL integrators, Pin diode/LED blocks installation.  ECAL racks need water leak testing before installation. Pressure? Flow? Little info available from Wiener.  Installation of remaining back planes for A-side end of September.  Sequence: PS cable chain support, Retaining “bac”, racks, gallery.  Do we install available FE cards in 156 or on platform?  Schedule of testing of FE on platform: Interference with VFE-FE cabling?  Should we start testing with racks on A-side while C-side is being cabled?  Temporary power and cooling availability on platform?  Any need for a PC ?  When do we need CRACK?  TELL1 availability for CRACK? Firmware?  Suggestion: Form a little group to plan the CRACK and TELL1 tests.

Debugging, testing  ECS control of electronics, HV, etc….  Data bases: Calo specific and configuration. Later conditions.  DAQ: TELL1 firmware.  Beyond TELL1? Farm? Software ?

Cabling  Cables patch panel to fixed point, fixed point to platforms. Procedure? Manpower?  Connectors?
