Minutes of the Geneva AMS group meeting on August 23, 2000
Geneva AMS group meetings
AMS-01 dismantling will begin next week (Tuesday 29 at 8.30AM) From Geneva
will be present there Eric+P.Bouvier or Manfred. After that planes will be
transfered to unige to dismount the ladders from the planes. In this sense
there is a request to dismount a "good" ladder to used it on the september
test beam. As soon Divic returns it will be done, in any case not before
the friday 1st september.
Still waiting response from italian companies how to solve burocratic
problems to send material from Italy to Switzerland.
Contraves send an "exorbitant" offer for plane modifications . In
negotiations with them via Prof. Hofer.
Legs offers have been received from some companies. At the end it has been
choosen one located at Meyrin. As they never built them some prototypes have
Last week, during TIM meeting, was held a meeting for thermal issues. From
tracker assisted Eric+NLR representative. From tracker point of view
everything was fine.
Davide and PL summarize the present situation about kapton. They present some
transparencies and a document with relevant inputs.
Test System progress on time. THis week was sent the analog part PCB
production at CERN that will be ready in a couple of weeks. THe two digital
boards available were "burned" in a test. JPR is trying to resucite them. On
the software side everything is progressing. Some problems have been
discovered with ALTERA Quartus package. It has been agreed to meet with AMS
people working with this software to exchange experience.
For the hybrid GA reports the delays on the missing components:
- VA: end of october... but still not a written confirmation
- Capas: middle September. No problem
- HCC: they are now boxing them in Taiwan.
- Conectors: 6-8 weeks.
Meeting with CAEN to finalize the technical specifications request for TDR
engineering. The unige request includes the engineering of the board, a plan
for testing and the production of prototypes (2 proto-1 and 6 proto-2). An
economic offer is waited for next week. The technical specifaction document
is available for everybody. Talk with Eduardo to get it.
Last week were built a L12 and a L2. Visual inspections proves that were best
placed than the mechanical prototype. Unfortunately the L2 ladder has a
"magnific" scratch. Hybrids has been choosen. These hybrids (v1.8) have non
standard placement of the holes in the conector. Next week they will be
bonded at CERN.
Final and confirmed dates 31.08-10.09. Part of the material is now at CERN
and Sylvanne is working to have a version of the DAQ software. According to
GA calculations around 600 Kevents will be recorded. The transfer of the data
include a "pedestrian ftp" = change physically the data disk and transport it
to the barrack to later on transfer the data with a real ftp to unige
machine. Tomorrow there will be the SPS meeting. Some unige representatives
will be there (GA,DV)
