Present: Charles, Gagik, David, Catherine, Alex, Jean-Marc, Franck,
Carlos, Matthieu, Eric, Malek, Sirish.
Franck/Installation:
- Electronics rack will move into the Hall on thursday afternoon.
Calorimeter unstacking will take place in the clean room on
thursday-friday. Blocks will be brought 5 by 5 to the Hall for
repair/stocking/restacking. DVCS detectors+platform will go into the Hall
early next week. RG213 will be moved at about the same time.
- Few remaining question to Jack: RG213 cable management (carriages?).
Sirish/Documents:
- Need to write COO, ESSAD, RSAD. TSOP may not be needed (will know
soon). ESSAD is what we should focus one. Each subsystem should write
about 1-2 pages describing installation and associated hazard and security
features.
- Still some money to spend quickly.
Gagik/Proton Array:
- repaired one of the worst-case block (horizontal tower). Only took
20min to replace the base which didn't work. Now, all PA channels are
fully operational.
Carlos/Calorimeter:
- Performed tests using continuous LED. Gain stability was better than
1% at 20uA and better at lower anode current.
- Performed stability tests, using chronical LED scans over a period of
10hrs. Clearly the system needs about 1-2 hrs to warm up. After this,
stability is better than 0.3% (might be even better, since the test is
limited by the statistical accuracy of the LED scan itself).
Eric/Veto:
- Patch panels are being repaired by local electronics group. Everything
will be ready by the end of the week.
- Writing 2 tech. notes, will be available shortly.
Alex/DAQ:
- problem with 2 ARS boards. Had to use spare. Now no spare anymore.
Faulty boards will be repaired/changed. Monday-Wednesday next week, Alex
and Bob will work together on DAQ, and integration into Hall A.
- Will try new PowerPC CPUs.
- Some remote switched have been ordered. Might need one more.
Franck/DB:
- script to send coda information to MySQL database on a run by run
basis has been written. |
