      - polarity
      Delay 250ns, tail pulse

08:30 - all system wide checks ok

- Temperatures ok - attachment 1

- good event statistics ok - attachment 2

- detector bias/leakage currents ok - attachment 3

DAQ continues to run - R1_1148

Merger ok - 4.6M data items/s

TapeServer ok - 43MB/s

08:55 Giovanna Benzoni - confirms contribution of light ions - attachment 4 see AOQ plots

09:19 zeroed all histograms

writing to file R1_1204

FRS on file 72

DESPEC to add AIDA XY hit patterns to online analysis histograms

09:35 beam stop

09:56 beam back

writing to file R1_1249

rate spectra - attachment 5

09:30 AIDA DAQ crashed - lost connection to aida05

power cycle and reset

09:40 AIDA ok now, writing to file R2

09:50 LS takes over

11.10 (German time)
      System wide checks produces some fails: 
      FEE64 module aida06 global clocks failed, 6 (screenshot6)
      This error is seen in RIKEN too, tried a RESYNC from master timestamp tab but error still there

FEE64 module aida06 failed
      FEE64 module aida07 failed
      Calibration test result: Passed 10, Failed 2 (screenshot7)
      Tried a recalibration for the two FEEs in FADC align & control tab but error still there

Rest of the checks pass
      Statistics (screenshot8)
      FEE temps okay (screenshot9)
      Leakage currents written to sheets (screenshot10)
      Merger ~4.5M data items/s
      TapeServer ~ 45MB/s

13.00 System wide checks produces same fails as last time: 
      FEE64 module aida06 global clocks failed, 6
      FEE64 module aida06 failed
      FEE64 module aida07 failed
      Calibration test result: Passed 10, Failed 2
      Rest of the checks are okay

Statistics (screenshot11)
      Spectra rate (screenshot12)
      FEE temps okay (screenshot13)
      Leakage currents written to sheets (screenshot14)
      Merger ~4.5M data items/s
      TapeServer ~ 45MB/s
      There is 1.5TB left on current drive

14.00 beam stopped to look at bPlast, have use the time to change slow comparator threshold
      Slow comparators in FEE9-12 raised to 0xd
