11.13 DAQ continues OK

ASIC settings 2019May19-17.54.03
      slow comparator 0xa

BNC PB-4 Pulser 
      Amplitude 90,000
      x5 attenuator IN
      Frequency 25Hz range
      t_r 100ns, tau_d 50us
      - polarity
      Delay MIN, tail pulse

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 statistics OK - see attachments 4
      10x < 20k, 21x < 50k, 24x < 100k - cf. yesterday 11x < 20k, 21x <50k

1.8.L spectra - see attachments 5 & 6
      nnaida1 74 ch FWHM, nnaida3 78 ch FWHM - cf. yeserday nnaida1 73 -> 74 ch FWHM
      p+n FEE64s 1.8.W spectra 20us FSR - attachment 7
      n+n FEE64s 1.8.W spectra 20us FSR - attachment 8
      1.8.L n+n spectra (log scale) no indication of light ions - attachment 9
      N.B. currently no ions through ZDS and no increase in background for DTAS
      This may/will change as online experiment starts to use ZDS from this evening

Check ASIC Control *all* FEE64s & ASICs
      zero all spectra
