Fixede748 Fri Jun 9 12:35:46 2017 AdrienMUST2Hardware CsI trip on T6
The detector were left on during the night. T6 CsI trip and cannot be switch on again. Once we established that all the MUFFEE works correctly we will start investigating the issue, perhaps coming from the distribution box.


NOW FIXED:

Not really clear what was the issue, Most likely a loose HT cables on the feedthrough flange.
Fixede748 Fri Jun 23 20:49:49 2017 AdrienMUST2General Restart
Chamber at 2e-5, cooling -9deg outside; -5 on copper LV off.

Starting BT and HV. No trip; normal current (1-2ua on DSSD; ~0.01 on CsI, still high current,9ua at 450V SiLi1 T5, other SiLi at 4-5ua).

DAS Config ok, passing I2C.

Start DAQ Ok storage off: all actor working 500kb/s, 200kb/s

GRU start ok; but receive no buffer. Kill all the daq and das, work ok.

Alpha look nice on all telescope that see the source (1-4 and half of 6/7).

All good for tonigh. let it run with storage off, waiting for the temp to set in before calibration.

Looking at the pt reaction and gating on z = 20 (solid blue) and z=19 (hashed orange) we see a total of three states.

Wednesday 30th May.
Run 2117 started at 8h36 ; Stop at 8h45: BEAM STOP.
Beam decreased at the end of Run 2116, still very low at the beginning of run 2117, 300 pps then 3 pps.
PCP told us that it should take a few minutes to recover it, but it will take more time (maybe 1/2 hour) to recover the beam,
due to vacuum problems before the target. The operators have to enter in the vault to check the equipments.
