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
  available ? M3R3 FC is ready All the others
  need the preparation of drawings
  (M3R4-M2R3-M5R4....)
• Honeycomb - We got samples for M1R3/R4 regions,
  cut at the right dimension and a quotation. Early
  2005 we should go for the purchase and the
  production.

• Wire in last months it occured several times
  (in LNF and at CERN) that the wire broke during
  the winding. The problem is being investigated by
  the Luma company. Probably it is related to a bad
  spooling.

Panel production rate
A rate of 250/month is mandatory to match the
chamber production schedule. To monitor the
production yield a data base on each INFN site is
operational. 2600 panels have been produced ?
on average a very good rate The yield appears
quite good approximately 90 .
Panels needed according to official plan
We are here

Chamber preparation prior to installation

• 1. Preparation in labs
• 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 Roma-2 and LNF for whole INFN production, at
  PNPI and at CERN.
• The first chambers will be equipped as soon as
  the CARDIAC boards will be available.
• 2. Shipping of MWPCs 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)
• 3. Tests at CERN
• Storage at CERN about 200 m2 available. Stored
  under gas flux.
• Tests check no-damage in transportation test on
  FEE and last test with HV\
• We have yet to deploy a detailed plan for these
  tests
• check the time and the personnel needed
• logistics at CERN and the infrastructure needed
  (gas, HV, etc...)

Trolleys and container for chamber storage and
transportation
Container with 6 trolleys of 18 chambers each
108 chambers.

Glue expiration date
Axson France certifies that the glue can be used
up to 24 months after fabrication
La presente per inviare in allegato il
certificato attestante il prolungamento data
scadenza del ns.prodotto Adekit A145/50 da Voi
acquistato. Colgo l'occasione per informarVi che
i ns. Prodotti Adekit A140 ed A145, a seguito di
test effettuati presso la ns. Casa madre, hanno
subito modifica di durata di vita che ora
corrisponde a mesi 24 dalla data di
fabbricazione. Distinti saluti Raffaella
