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 Encoding: HTML ELCode plain Suppress Email notification
