09.28 System wide checks - aida06 global clock failure (check clock status)

- aida02 , aida04, aida06 fail calibration (ADC calibration)

- SYNC error counter ok

- SYNC pulse check ok

- 'collect memory information from FEE64 Linux' still returns scripting error

- WR decoder test passes

09.33 good event statistics ok, except aida09, aida10 running hot. (attachment 1)

FEE temperatures ok (attachment 2)

detector bias/leakage current ok (attachment 3)

09.38 screenshots of NewMerger tab, Merger/Tape HTTPd and NewMerger terminal (attachments 4, 5, 6)

10.05 1.8.L pulser peak spectra (attachment 7)

10.13 1.8.W waveform spectra (attachment 8)

21.13 Beam on

AIDA DAQ running - writing to file R9 in directory 290319

System wide checks - same as above

good event statistics ok - although rates on 9,10,11,12 have dropped (attachment 10)

ASIC check load performed

FEE temperatures ok (attachment 9)

detector bias leakage currents ok (attachment 11)

Scintillator 41 -> approx 1000 ions/s, 11 second super cycle (beam on 10s, beam off 1s)
      c. 130-150MeV/u 107Ag ions incident on plastic scintillator + AIDA DSSSD

21.36 High energy spectra for aida09 - (attachment 12)

High energy spectra for aida11 - (attachment 13)

Low energy spectra - (attachment 14)

1D hit pattern - (attachment 15)

21.53 ASIC control settings - see for slow comparator threshold, fast comparator threshold (HEC) and fast
      comparator threshold (LEC) (attachment 16)

NewMerger screenshot - working (attachment 17)

22.00 ASIC options - including directory path to saved ASIC settings (attachment 18)

22.09 beam stop
      TapeServer stopped, restarted not writing to storage
      one complete file produced R9_0 (2.0 GB)
      plus R9_1 (154 MB)

*NOTE FROM 02/04/19 - DEGRADER in front of detector, silver beam not observed, just unidentified light ions.
