00:00 - CA takes over 00:15 - stats/database/ucesb ok - attachment 1 - another burst of bad timestamp error messages in NewMerger terminal - but all FEE64 still ok - attachment 2 - Merger/TapeService ok 00:21 - beam still off while UNILAC having problems 00:26 - beam is back - rate spectra - attachment 3 00:32 - ucesb following beam return - attachment 4 - implant rates reaching highs of ~1kHz 00:35 - Grafana leakage current monitor last 6 hours - attachment 5 01:00 all system wide checks ok stats ok - attachment 6 temperatures ok - attachment 7 detector bias / leakage currents ok - attachment 8 db check ok / ucesb ok still observe periodic bursts of bad timestamp errors in NewMerger terminal - FEE64s still linked with merger ok 01:30 AIDA crashes just as I make check, most FEE64 lost connection -> powercycle and restart MIDAS 01:53 AIDA reset completed - writing to file NULL/R48 01:56 all system wide checks ok except FPGA error counter Base Current Difference aida12 fault 0x0 : 0x1 : 1 FPGA Timestamp error counter test result: Passed 11, Failed 1 If any of these counts are reported as in error The ASIC readout system has detected a timeslip. That is the timestamp read from the time FIFO is not younger than the last ADC calibration FEE64 module aida04 failed FEE64 module aida05 failed Calibration test result: Passed 10, Failed 2 If any modules fail calibration , check the clock status and open the FADC Align and Control browser page to rerun calibration for that module 02:01 good event statistics ok - attachment 9 temperatures ok - attachment 10 detector bias / leakage currents ok - attachment 11 db check / ucesb ok 02:20 beam stop 02:21 beam back 02:30 stats/ucesb/db checks all ok 03:00 stats/ucesb/db checks all ok - attachment 12 03:30 stats/ucesb/db checks all ok 04:00 system wide checks ok, except; ADC calibration FEE64 module aida04 failed FEE64 module aida05 failed Calibration test result: Passed 10, Failed 2 If any modules fail calibration , check the clock status and open the FADC Align and Control browser page to rerun calibration for that module FPGA errors Base Current Difference aida12 fault 0x0 : 0x9 : 9 FPGA Timestamp error counter test result: Passed 11, Failed 1 If any of these counts are reported as in error The ASIC readout system has detected a timeslip.
