Pre-commissioning

  FMD2, then FMD1)
• - complete test with RCU, DDL, DATE,
  TTC/LTU, cooling
• (but not final CAEN LV and HV)
• - basic DCS panels, tested on simulated
  CAEN and real RCU/DCS card
• _at_CERN (Jan-Feb 2007)
• - retest as above, but with final CAEN
  power supplies
• Status of pre-commissioning (_at_NBI)
• - FMD3 mechanics ready, FMD2 starting
  production
• - all detector modules in house
• - TTC/LTU being set up
• - cooling plates in production
• - DCS work starting
• - complete read-out working

Electronics Racks

• Locations of racks in the cavern drawings of
  rack content including rack patch-panels and
  possible communication lines between racks and
  entry point of cables (top, bottom ?)
• - Rack O13 contains one EASY 3000 crate
  with 48 V power supply etc
• one patch panel to distribute the LV cables
  from 10 digitizers and 3 RCUs to 4 low
  voltage modules
• - Rack X06 contains one SY1527 crate
• one patch panel to distribute the HV cables
  from 70 modules
• and 6 high voltage modules
• Schedule for arrival of electronics and
  individual rack components at CERN.
• - Power supply crates hopefully early 2007
• - Power supply modules before August 2007
  delivery schedule unknown
• - Patch panels to be mounted together with
  cable connectors
• Electronics commissioning
• - Power supplies to be installed and
  commissioned together with FMD3

Detector Arrival _at_ CERN

• Installation dates FMD3 16-20 February 2007
• FMD2 07 March 2007
• FMD1 03-05 July 2007
• When will the detector arrive at CERN ?
• - before mid January 2007 (FMD3 and FMD2, FMD1
  later)
• What are the dimensions of the transport cradle
  that must be brought to the place of
  installation ? How will it be brought there?
• - 2 times 1x1x1 m3 by car
• How many people will participate in the
  installation ?
• - 6-8 people (physicists and technicians)
• How many days before installation will the team
  arrive ?
• - early-mid January for lab. test 3-4 people
• - for installation above 3-4 people

8
Cables Patch panels

• Status of cable, fibre and connector ordering.
• - C side cables on absorber done, remaining
  defined
• but cables not pulled. Fibres not pulled.
• - A side defined, but missing final cable
  lengths and final patch panel designs.
• Plans for cabling, connector and cable testing
  activity by subgroup.
• - NBI - cables on absorber and service
  chariot
• - all cable connectors
• - full cable testing
• - CERN - pull long cables and all fibres
• Needed patch panels and status of patch panels.
• - Still to be done panels on A side (PP2, PP1,
  PP0)
• panels in racks (LV and HV distributions)

9
Installation (1)

• Minimum status of services at start of
  installation.
• - all cables and fibres ready and tested
• - LTU/TTC running
• - DAQ running
• - CAEN HV and EASY LV crates and some modules
  delivered
• - preferably cooling water from TPC heat screen
  system
• Installation tooling provided by the subdetector
  group.
• - support for cones during assembly
• Other Infrastructure needed.
• - full ITS installation infrastructure
• Installation scenario day by day.
• - Before installation date install and cable
  RCU modules
• - FMD3 3 days mechanical installation, then
  complete test
• - FMD2 1 day mechanical installation
• 1 day (12/03/2007) set aside for complete
  test after the cable hook-up

10
Installation (2)

• Tests and verifications during installation for
  cables, fibers and cooling lines.
• - cables etc should be tested before
  installation
• - FMD3 should be verified through to the racks
  and counting rooms (with DCS and DAQ)
• - FMD2 cannot be cabled until TPC is in place
• ideally detector should be tested with the
  commissioning electronics
• Not clear what is possible with temporary
  cabling, power etc.
• Alignment requirements
• - assured at required precision by ITS
  installation scenario
