FEDv2 Pre-Series

• Q3/2004 Manufacture and commission first 2
  FEDv2s. Both at CERN.
• Q4/2004 Prepare pre-series production of 25
  FEDv2 boards.
• Final tests of FEDv2 design
• Fine tuning of Front-End analogue passive
  components. Change Rload 62R (now verified on
  FEDv2).
• Q1/2005
• Pre-series of 5 20 (to verify full VME crate
  operation and then deliver to LSA centres)
• 5 boards delivered to RAL during Tracker week
  Feb.
• 4 boards are good. (1 sent to CERN , 1 at
  Imperial)
• 1 board traced damaged BGA sent back for rework
• 10 further boards arrived end of last week under
  test.
• 10 remaining boards expected this Friday.
• Summary Pre-series proceeding to original
  schedule.
• 3 FEDv2s now at CERN. A few more could be sent
  before May.
• Larger deliveries after Full Crate Test.
• FEDv1s
• Upgrade FEDv1s (minor mod to be compatible with
  FEDv2, except no S-LINK).

Full Crate Test at RAL
FED Tester Crate
FED Crate

• To verify operation 16 FEDs. And later for
  production tests with slink/optical/ttc systems.
• Received Rack (arranging for chiller)
• TTC interface to FED Tester ready by Easter
  Software ready to test now
• Additional Equipment still needed in April
• 2nd LHC 9U Crate SBS Crate Controller adapter
  (PCI-X)
• And will need (11) more crates for Assembly
  plant tests starting this summer

Other Items

• Further soak tests of SLINK readout in extreme
  data rate conditions.
• Finalised design of 6U VME SLINK Transition card
  this month. Making 6 off.
• SLINK cables (see talk by Attila)
• Several improvements to FED firmware ready
  needed for final CMS operation (updated Technical
  Document).
• New unambiguous FED channel numbering scheme
  adopted (suggestion by Francois to match optical
  cabling)
• Other equipment CAEN interfaces, 6U-gt9U adapters
  ?
• TTC splitters, switch to single mode fibres
  switch to TTCci?
• B904 preparations ?
