  ALICE. (Luciano Musa 30).
• 10.05 Greek DAQ effort in ALICE. (Martha
  Spyropoulou-Stassinaki 10)10.15 FMD status
  of industry contacts  and ideas for FE and BE
  electronics solution. (Borge Svane Nielsen 40)

  integration with trigger, DAQ, Back End
  electronics, slow control, alignment and survey,
  etc., discussion on planning up to TDR. (JJG)

FMD progress plan

• 1. Update, revise all simulations for actual
  geometry and beam pipe layout(started, in
  progress)
• 2. Explore details of Si layout and manufacture
  details with companies(started, in progress)
• 3. Explore in simulations consequence of ITS
  cabling. Not started yet, but now in principle
  possible to start after first ITS materials
  balance by P.L.Barberi.
• 4. Once Si manufacture details and specs are
  clearer, return to IDEAS and fix more detailed
  specs for FE electronics (after summer 2002)
• 5. Develop drawings for mounting of Si detectors
  onto interface agreed withITS (3rd cone etc...).
  Interface not yet fully agreed. Fall 2002
• 6.Describe integration and installation sequence.
  Still far from clear. Hand in hand with ITS.

FMD

• 7. Define cabling better. Must wait for next
  round of discussing with FE company.
• 8. Move towards ordering of prototype Si and FE
  system. (fall 2002)
• 9. Start work defining Back End (BE) electronics
  and interfacing withDAQ.We are missing people
  for this. Some discussion with 2 potential
  groups(Zagreb , Krakow) are in progress. Outcome
  unsure at this moment. (fall2002).
• 10. First prototyping and test with e-beam.
  (early 2003).
• 11. Prototype test at RHIC/BRAHMS (late 2003-
  RHIC run IV).I would believe that the time for
  a TDR is between items 9 and 10.
  Thisrealistically brings us into the late spring
  of 2003.

FWD detectors TDR status

• - A draft (v1.3) of the FMD document was
  distributed at last ALICE week - next version
  will soon appear on our Web page.- A recent -
  not yet published - ALICE note on V0 will be
  forwarded toBSN.- The published ALICE note on
  T0 needs updating before it can be turnedinto a
  draft for the T0 TDR.- In the September ALICE
  week, we should have the next versions of
  3separate documents. Discuss the structure of
  the combineddocument.- The aim is to have a
  draft TDR in December 2002, and an edited draft
  inFebruary 2003.

Action items

• Clarify installation issues between beam pipe,
  ITS and FMD by end of 2002.
• F. Tosello to give an update on ITS services at
  September TB
• F. Tosello and A. Morsch to update simulation
  input from ITS by autumn 2002
• Seek common back end electronics solutions for
  FMD, VO, TO by autumn 2002.G.Stefanini involved.
