Material Procurement

1

• Material Procurement
• Construction material All the material has
  been ordered with some spare (10)
• Delivered material
• PNPI M3R4 Panels 70 - HV bars 100 - FR4
  frames 100
• PNPI M2R4 Panels 20 - HV bars 100 - FR4
  frames 100
• PNPI M4R4 Panels 0 - HV bars 90 - FR4
  frames 0
• CERN Panels 60
• INFN M3R3 completed M2R3 completed M5R4
  Panels 20
• HV bars 40 FR4 frames 100 Other elements
  100
• M1 panels 0
• Faraday cage Final FEE board dimensions M3R3
  ready All the others need the preparation of
  drawings (M3R4-M2R3-M5R4....)
• Honeycomb panels - We got samples of M1R3/R4
  regions, cut at the right dimension and a
  quotation. Early 2005 we should go for the
  purchase and the production.

• Panel production
• A strict monitoring of the panel quality and of
  the production rate is performed
• with regular visits (every two weeks) to the
  company and with checks at the production site.
• This is certainly the most critical item on the
  chamber and the production has to be followed
  closely.
• The required planarity is very demanding (- 90
  micron) especially on the largest panels (400 x
  1600 mm2)
• A rate of 250/month is mandatory to match the
  chamber production in the various sites (see next
  plots).
• To monitor the production yield a data base on
  each INFN site is operational.
• This tool helps also to have a more efficient
  chamber production.
• The yield appears quite good approximately 90
  .
• We are also developing a tool to recover non
  planar panels (especially the gold plated one,
  which are the most expensive).

Panels needed at production sites according to
official plan

• Preliminary plans to equip and to install
  chambers
• Once the chamber have been tested with
  radioactive source, FEE electronics, LV and
  Faraday Cage must be assembled on chamber (and
  tested).
• Part of this work will be done at the production
  sites (at LNF, for whole INFN, at PNPI and at
  CERN).
• Probably, for PNPI chambers, electronics will be
  assembled at CERN.
• The first chambers will be equipped as soon the
  CARDIAC boards will be available.
• Shipping of INFN chambers to CERN in special
  trolleys with shock absorbers stocked in a
  container (see photo).
• Shipping of PNPI chambers in wooden boxes
  (CSC-CMS like)
• Reception at CERN about 200 m2 available (not
  so much)
• Gas flux last test with HV Installation on
  the detector
• We have yet to deploy a detailed plan for this
  part of the installation
• check the time and the personnel needed
• logistics at CERN and the infrastructure needed
  (gas, HV, etc...)
• setup the procedures and the team for the
  installation on the detector (integration among
  various labs)
