Tom Shea
Present: P. Cerniglia, T. Clifford, C. Degen, J. Mead, B. Oerter, B. Olsen,
V. Ptitsyn, T. Satogata, T. Shea, D. Trbojevic, W. MacKay
Phil presented the usual table summarizing production status and reminded us
that an html version is updated twice per week on the instrumentation web
server:
Status Table
In summary, BPM modules have been delivered to all injection line buildings
and ring equipment buildings at all IRs. Sectors 4 and 5 are also complete.
With improvements to the test system, yield is now above 90%. Pending a final
parts count, all circuit boards should be in house by mid-February. The Heliax
pulls could still be a problem as they are only 20% complete. 1394 cable
deliveries are behind schedule, but ahead of module installation.
Brian Oerter announced that the beam sync master is installed in 1004a and
should be running by the end of the week. First article beam sync fanouts and
reset chassis are also available now. The reset chassis will be tested first in
alcove 5a.
Tom Clifford mentioned that he needs the list of required beam sync events.
There was a question about the flexibility of event assignments (This has been
resolved as Tom Kerner later confirmed that the master includes a lookup table
- T. Shea)
Todd and Tom clifford confirmed that we will be able to observe FEB extractions
late into February. Preparations continue for system integration tests in
A-Trailer. Chris and Joe predict that we will be ready to measure beam by next
week. The module will will be attached to UB2, trigger on the REL, and run in
ATR mode. (Tom Shea later confirmed with John Gould that the Beam Sync Clock
could be patched to A-Trailer. This would allow testing of injection mode
before March.)
Chris showed a LabVIEW application monitoring BPMs in sector 4. This app uses
Don Shea's SNAP memory server that runs in the FEC. With performance testing
complete, all diagnostic applications are being modified to use this server.
The ADO has been tested with BPM modules in the lab. Bob Olsen needs a stable
environment for further ADO testing.
Vadim and Todd said that the IR BPMs from Q4 to Q4 are the most critical along
with the injection areas around Q9. Vadim proposed a sparse population scenario
that removes every third arc BPM in each plane.
The following decisions will be made around the third week of February:
- beam or no beam
- predicted number of instrumented BPMs
- single turn only (ATR mode) or 1000 turn operation (add injection mode)
Action items:
- Confirm heliax pull schedule with Bob Lambiase (Phil)
- Check on 1394 cable deliveries (Phil)
- Deliver beam sync event list to Tom Clifford (Tom Shea/Waldo)
- Prepare a list of potentially uninstrumented BPMs (Vadim)
- Configure a system for Bob Olsen's use in 1002a (Chris)
