08:19 System wide checks all ok Baselines reset on WR and FPGA checks for the start of the day Statistics ok - attachment 1 Temperatures ok - attachment 2 Bias and leakage currents ok - attachment 3 09:03 During the reset last night I repaired the OptionsDB for aida02 from the Options.Pristine directory. No corruptions have been noted since 10:10 System check, clcock and ADC ok Base Current Difference aida07 fault 0xfb3a : 0xfb3d : 3 White Rabbit error counter test result: Passed 11, 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 FPGA and memory check ok Statistics ok - attachment 4 Temperatures ok - attachment 5 Bias and leakage currents ok - attachment 6 10:39 Fission fragments were punching through AIDA This was even with the maxmimum degraders in place They are now placing a thick plate in front of AIDA to block the fragments while they beam tune. 11:38 They have found the issue with the degrader and have corrected it. We now see next to no implants in AIDA as expect. Histograms reset at around 11:35 Layout 2 shows very few implants in 5 minutes - attachment 7 12:08 The high implantation rates of ions into AIDA is clearly seen in the large transients on the leakage currents - attachment 8 This was a large amount of dose going into the detectors which we should try to avoid 13:25 system check, clock and ADC ok Base Current Difference aida05 fault 0xc879 : 0xc87b : 2 aida06 fault 0x323c : 0x323e : 2 aida07 fault 0xfb3a : 0xfb3f : 5 aida08 fault 0xd3d6 : 0xd3d8 : 2 White Rabbit error counter test result: Passed 8, Failed 4 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 ok - attachment 9 Temperatures ok - attachment 10 Bias and leakage currents ok - attachment 11 FPGA and memory check ok 16:10 system check, clock and ADC ok Base Current Difference aida05 fault 0xc879 : 0xc87b : 2 aida06 fault 0x323c : 0x323e : 2 aida07 fault 0xfb3a : 0xfb3f : 5 aida08 fault 0xd3d6 : 0xd3d8 : 2 White Rabbit error counter test result: Passed 8, Failed 4 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 ok - attachment 12 Temperatures ok - attachment 13 Bias and leakage currents ok - attachment 14 FPGA and memory check ok Encoding: HTML ELCode plain Suppress Email notification
