1. Status Brussels GANTRY
O.Bouhali, J.D’Hondt, J. Heyninck, C.Vandervelde, L.Van Lancker, J.Wickens
Gantry meeting CMS – June 2004
Assembly of R3 modules
good precision (introduced corrections)
lacking hybrids (only 10 left)
Assembly of R6 modules
via dry assemblies we have estimated corrections
will produce some R6 modules this week for tests
Assembly of R5 modules (R5N and R5S)
for R5N the final commissioning of the plate will happen this week
some more work is needed for R5S

2. R3 module production
Precise and stable production of about modules up to now (total ~700)
some bad modules in the beginning of the production
introduced ‘off-line’ corrections which are applied during assembly
most of them shipped to Hamburg or Karlsruhe
CMS TEC specifications

3. R6 and R5 module assembly
R6 modules : we have determined the final ‘off-line’ corrections for one plate
still checking the stability of these corrections
expected to be ready for precise and stable production today !!
making ourselves ready for the HPK sensors to arrive for test soon
(change of sensor mask)
R5N modules : we are almost ready with one plate
final estimate of the pin positions
this week we finalize the estimation of the ‘off-line’ corrections
expected to be ready for some precise and stable production by next week !!
R5S modules : to be finalized soon

4. Residual issues Gluing of 2D label on frames ??
we wait for a tool from Aachen to position this label with ~0.5mm precision
We are installing a second back-up PC in case of sever accident
can we already include the spare expansion card ??
used to be positioned here
proposal to put it here (Aachen)
(reduces the problem of overlapping legs during
module mounting on petals)
(different tool for each module type ??)

5. Available components R3 modules : hybrids # 10 HPK sensors # 326
ST sensors # 58 (W6A) # 92 (W6B)
R5 modules :
hybrids # 30 (R5S) # 10 (R5N)
ST sensors # 37 (W5A) # 25 (W5B)
soon some HPK sensors are supposed to arrive for testing !!

6. Summary
R3 modules :
If hybrids arrive we just continue the production… (1 plate)
R6 modules :
Ready (~) today for production (1 plate commissioned)
Smaller details to deal with in order to make the production easier
R5 modules :
The work on R5N to be finalized (1 plate ready soon)
More work needed for R5S (1 plate ready within few weeks)
new technician arrived and being trained for the production
