16:00 p+n threshold 0xc (120keV)
n+n threshold DSSD2 0x20 (250keV) ASICS 1-3, 0x64 ASIC4
n+n threshold DSSD2 0x19 (250keV) ASICS 1-3, 0x64 ASIC4
Dead time has increased from yesterday. From the elog this appears to coincide with their changing of the spill structure.
17:30 Grafana informs us we have hit 10uA on DSSD2. This is fine with the size of the detector
18:12 Gregor noticed that at 18:02 the rate in AIDA increased. This could be related to the autofill starting around now.
The deadtimes in FEE6 and 8 have risen to around 6.25%.
Looking at this mornings and yesterday evenings fill times this behavior isn't observed
18:30 The rates still seem to be increased so is unlikely to be due to the filling which finished at least 10 minutes ago
18:49 Have tried raising the thresholds to 0x1a for the y side strips of DSSD2
This has brought the deadtime of AIDA06 down to 5.53% (This seems to have just been a statistical fluctuation and the rate went back up again in the next file)
18:12 Raised threshold to 0x1b for ASIC1-3 of FEE6 and 8
18:15 System wide checks ok except WR as usual
Base Current Difference
aida05 fault 0x500 : 0x56d : 109
White Rabbit error counter test result: Passed 15, Failed 1
Understand the status reports as follows:-
Status bit 3 : White Rabbit decoder detected an error in the received data
Status bit 2 : Firmware registered WR error, no reload of Timestamp
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR
Statistics increased at 18:02 still working on - attachment 2
FEE temp - attachment 3
Bias and leakage current - attachment 4
20:51 System wide checks ok - WR same as before
Statistics still high - attachment 5
Temperatures ok - attachment 6
Bias and leakage currents ok - attachment 7
22:52 Statistics still high - attachment 8
Temp ok - attachment 9
Bias and leakage current ok - attachment 10
System wide checks ok - WR difference still 109 |
