Subject: 08:00-16:00 Thursday 25 April 
09.56 DAQ continues data file S100_alpha/R18_387
      FRS switching settings

      DSSSD bias & leakage current OK - attachments 1

      FEE64 temperatures OK  - attachment 2
       aida02 ASIC temp - known fault

      All system wide checks OK *except* as shown - attachments 3-5

      WR timestamps OK - attachment 6

      ADC, PAUSE, RESUME & Correlation Scaler data time stats - attachments 7-10

      per FEE64 Rate spectra - attachments 11

      per p+n FEE64 1.8.L spectra - attachments 12-13
       aida09 pulser peak width 57 ch FWHM 
       common x/y scale => peak height proxy for width => all p+n FEE64s similar pulser peak widths

      per n+n FEE64 1.8.L spectra - attachment 14

      per FEE64 1.8.H spectra - attachments 15-16

      per FEE64 1.8.W spectra - 20us FSR - attachments 17-18
       only aida08 & aida09 currently updating - ASIC check load and/or DAQ STOP/GO required?

      Merger, TapeServer etc - attachments 19-21

      BNC PB-5 settings - attachment 22

10.07 data file S100_alpha/R20
      new run for new FRS setting

10.08 all histograms, stats, merger stats and data link stats zero'd

10.10 ADC data item stats (beam OFF) - attachment 23
      11/16 < 20k, max 129k (aida08)

10.31 analysis of data file R18_349 (closed 06.00 this morning)
      max deadtime 12% (aida04)
      no timewarps
      HEC data item rate 1.7kHz

11.00 tuning 168dy FRS setting
      ucesb - attachment 24
      spill length 3.5s, extraction time 1.5s

11.30 degraders now set to implant in AIDA DSSSDs
      high rates expected 

      per FEE64 Rate spectra - attachment 25

      ADC data item stats - attachment 26

      Merger etc - attachment 27
      in spill rates to MBS up 30+Mb/s, 2.5M data item/s merged

      DSSSD bias & leakage current - attachment 28
       c. few hundred nA step in leakage current 

      analysis of data file R20_33 - attachment 29
      max deadtime 18% (aida08)
      no timewarps
      HEC data item rate 4.1kHz (c. 2.4x previous FRS setting)

      Correcting for spill cycle => 5.9kHz in spill (online analysis shows no HEC events observed outside spill)
      assume typical HEC event multiplicity = 3 => implant rate ~ 2.0kHz in spill or 6800 implants per spill
      SC42 L/R currently report c. 4.5kHz

      Note that we currently see a higher fraction of events in DSSSD#2 cf. previous setting so multiplicity assumption may be low
      If we assume multipicity = 6 => implant rate ~ 1.0kHz in spill or 3200 implants per spill

      we are probably somewhere in between

12.50 DSSSD bias & leakage current - Grafana - attachment 30
       leakage current ramping, spill micro structure observable

      FEE64 temperatures OK - attachment 31

      ADC data item stats - attachment 32

      per FEE64 Rate spectra - attachment 33

      Merger etc - attachment 34

14.56 analysis of data file R20_106 - attachment 35
      max deadtime c. 18% (aida04 & aida08), c. 12% (aida03), c. 11% (aida06), c. 9% (aida02 & aida13), c. 6% (aida05), all others <2%
      no timewarps
      HEC data item rate 4.2kHz


15.40 DSSSD bias & leakage current - Grafana - attachments 36-37
       leakage current ramping, spill micro structure observable

      FEE64 temperatures OK - attachment 38

      ADC data item stats - attachment 39

      Merger etc - attachment 41

      ucesb - attachment 42

15.57 all histograms zero'd
