08:00 DAQ continues ok - writing to file R13_120 Merger ok - 4.6M data items/s TapeServer ok - 43 MB/s 08:03 - all system wide checks ok - Temperatures ok - attachment 1 - good event statistics ok - attachment 2 - detector bias/leakage currents ok - attachment 3 08:08 ASIC settings 2019Dec19-16.19.51 DSSSD#1 slow comparator 0xa DSSSD#2 slow comparator 0xa DSSSD#3 slow comparator 0xd BNC PB-5 Pulser Amplitude1.0V Attenuation x1 Frequency 2Hz tau_d 1ms - polarity Delay 250ns, tail pulse 08:32 CA briefly lost network connection - back now 08:42 DESPEC on file 102 09:24 Rate spectra - attachment 4 09:32 HEC spectra - attachment 5/6 beam off - writing to file R13_243 09:42 merger bad timestamp errors - attachment 7 all system wide checks ok 10:30 NH - Beam was down, I try the new merger from Vic again (R14) I made a mistake and had to powercycle fees as they got stuck! aida10 seemed to reboot itslef After fixing my mistakes, all running with new merger and rate 15 MB/s (R14) It all looked OK even going to MBS/Go4 I reverted back to original hot merger, R15 and look at the data. Beam is now back and I return AIDA to shifters :) 11.30 System wide checks okay except ADC calibration: FEE64 module aida07 failed FEE64 module aida10 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 Reran calibration for both FEEs but still fail Statistics (attachment8) Rate spectra (attachment9) FEE temps (attachment10) Leakage currents written to sheet (attachment11) Tapeserver ~33MB/s Merger ~ 3.4M items/s AIDA file R15_92 11.55 Beam off for a couple minutes but back now 12.00 New Merge terminal disappeared so stopped daq and restarted, and also restarted MBS back working Now writing to R16 Merger ~ 4.5M items/s Tapeserver ~44MB/s 12.41 no beam 13.00 DAQ crashed (aida03 no responding), AIDA recovered from power cycle while beam is down Beam is back now, forwarding to MBS Merger ~ 45M items/s Tapeserver ~44MB/s Writing to R17 13.20 System wide checks okay except ADC calibration: FEE64 module aida07 failed FEE64 module aida10 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 Statistics (attachment12) Rate spectra (attachment13) FEE temps (attachment14) Leakage currents written to sheet (attachment15) Tapeserver ~45MB/s Merger ~ 4.4M items/s 14.27 beam off file R17_115 back a couple minutes later 14.40 no beam again back at 14.46 15.40 System wide checks okay except ADC calibration: FEE64 module aida07 failed FEE64 module aida10 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 Statistics (attachment16) Rate spectra (attachment17) FEE temps (attachment18) Leakage currents written to sheet (attachment19) Tapeserver ~44MB/s Merger ~ 4.4M items/s 15.52 beam down R17_221, back at 15.58 R17_229 16.07 Beam down 16:20 Removed S480 files from /media/1e... and /media/SecondDrive Set merger to no output and stopped tapedata. Changed symbolic link of /TapeData to /media/1e..... Restarted tapedata and the merger with outputting to file R20 Local DESPEC was made aware of this before carrying out and stopped the run. Beam back 17.12 beam down for a couple of minutes R20_90 17.40 System wide checks okay except ADC calibration: FEE64 module aida07 failed FEE64 module aida10 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 Statistics (attachment20) Rate spectra (attachment21) FEE temps (attachment22) Leakage currents written to sheet (attachment23) Tapeserver ~45MB/s Merger ~ 4.5M items/s Encoding: HTML ELCode plain Suppress Email notification
