CMS RPC production scheme Revised version
Assumptions for phase I (end 2003/start 2004)
Glossary

• PV is devoted to chamber test only and to
  bakelite QC
• An additional external company (HT) will be
  involved in the assembly (under the control of
  NA group)
• Gap production and quality control remains
  mainly with the BA group with some help from the
  NA group
• Chamber assembly at GT remains with the BA group
  only
• BA remains as chamber test site and an assembly
  sites for RB3 chambers in the first phase.

PV Pavia INFN group NA Naples INFN group BA
Bari INFN group GT General Tecnica
(Frosinone) HT High Tech (Caserta) CERN CERN-ISR
SO Sofia group PU Peking University group
More assumption for phase II (2004/2005)

• SO becomes an assembly and test site for RB3 in
  the phase 2 BA site can be considered as back
  site for RB3 assembly in case of difficulties
• RB1 chambers are built in Italy (GT) and tested
  at PV
• A way to involve physicists from PU in the RB1
  test should be envisaged
• RB2 are built at HT and tested at BA.

RPC chambers production plan phase I
NA group is involved in the RB1/RB2 assembly at
HT and the tests at BA PV group is involved in
the test of chambers RB1 BA group is involved
in the assembly and in the test at BA. BA
group is also involved in the assembly at GT.

ISR
A test bench is being prepared at ISR Limited
test capability (4 chambers) with
cosmics Sampling test with cosmics Extensive
tests on current and rates chamber by chamber 1
physicist 1 technician as minimal team
permanently at ISR starting in June More
technicians during the installation (help from
DT?)

Critical issues
GT production of double gaps and chambers not in
parallel Bari chamber test at the moment takes
more time then foreseen. Improve trigger to take
date simultaneously on forward and back part
Pavia the test facility will be ready in the
summer Cern GIF activity will slow down the ISR
preparation. X5 managers have decided to clean au
the area and reinstall experiment during middle
April - middle May!!!

ISR 1-2 physicist 2 technicians from
BA/NA/PV teams
Bari man power look saturated help from SO for
the RB3 assembly and test. Moreover a more
constant presence of people from Sofia could
free Bari people for ISR work.
At the start up ( first 1-2 months) Bari
expert will participate

Needed
Bari 12 month-physicist from SO
art. 15 expiring end of year. Absolutely needed
to renew the contract Pavia 6
month-physicist from PU Napoli Roscilli
involved in the cable layout project. Resources
needed to have him at Cern for
a while
