08.03 DAQ continues - AIDA file RIBF148/R5_117
      165Pm BigRIPS setting + 3mm Al degrader
      
08.10 all system wide checks OK *except* nnaida7 fails ADC calibration

      detector biases & leakage currents OK - see attachments 1 & 2

      FEE64 temperatures OK - see attachment 3
      good event & AIDA discriminator statistics OK - see attachments 4 & 5

      Merger OK - see attachment 6
      TapeServer OK - see attachment 7
      no errors or warnings shown by server terminal sessions 

08.16 analysis of file RIBF148/R5_116 - see attachment 8
      max deadtime nnaida19 ~ 1/420 ~ 0.25%, no timewarps

08.44 MIDASsort online spectra zero'd

08.56 1.8.W spectra 20ms FSR - see attachments 16 & 17
      observe slow transient recovery per 33nF a.c. coupling but 'sawtooth' transients appear to be absent/rare

10.27 Beam off - enter F11 to change BRIKEN amp gain
      Correlation scaler pulser trigger frequency changed from 100Hz to 10Hz to minimise BigRIPS DAQ deadtime
      Note - we will observe both edges of pulser trigger doubling the apparent frequency and the TDR data format
      analyser reports each 16-bit word of the 48-bit correlation scaler so weill observe 6x frequency or 600Hz
(previously)
      or 60Hz (now).
