Dear all !
Harry has asked for a plan splitting the 12 different chamber types to the 4 labs involved in construction in 2004. Some chamber types will be listed with a primary and a secondary production site, in which they will be produced in parallel. This ensures the chamber production for all the 3 supermodules will be completed by end of this year.
Number of different ROC types to be built in 2004
DUB 6 : L[1-6]C0
BU 3 : L[1,2,6]C1
GSI 3 : L[3,4,5]C1
HD 6 : L[1-2]C0, L[2-4,6]C1
Primary + Secondary production site overview
C0 C1
------------------------------------
L6 DUB HD +BU
L5 DUB GSI
L4 DUB GSI+HD
L3 DUB HD +GSI
L2 DUB+HD BU +HD
L1 DUB+HD BU
Number of ROCs to be built for 3 SM in primary + secondary sites
C0 C1
------------------------------------
L6 3 DUB 8 HD + 4 BU
L5 3 DUB 12 GSI
L4 3 DUB 4 GSI+ 8 HD
L3 3 DUB 8 HD + 4 GSI
L2 3 DUB + 3 HD 4 BU + 8 HD
L1 3 DUB + 3 HD 12 BU
List of labs participating in construction in 2004,
and minimum number of ROCs built in 2004 for 3 SM + Testbeam
DUB Dubna 18
BU Bucharest 20
GSI Darmstadt 20
HD Heidelberg 38
----
Total 96 (including 6 chambers for testbeam 2004)
The numbers agree all with the ones presented by Harry on the TRD collaboration meeting at GSI this year. The number of chamber types to be built in every lab may vary in case of unexpected delay in part supply. Repartition of ROC types is not forseen to change in 2004.
Best regards,
David

Dear David,
thanks for the tentative distribution list of ROCs.
I have a few questions/comments:
- I dont understand what is primary/secondary production site
- According to your scheme, the six test beam chambers are
not part of the 3 SM batch, but ADDITIONAL six chambers
to be produced (early) this year. Was this decided? I'm not
sure we can afford it.
Couldn't you foresee to use 3 SM chambers for the test beam?
- I am still a bit unhappy about the fact that three different
chamber types are foreseen in Bucharest and GSI. Could you
send us the scheduled delivery dates for the pad planes?
Regards, Harry
