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

       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

      back a couple minutes later

14.40 no beam again back at 14.46

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
