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% .

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.
