02.37 DAQ stalled - USB-controlled ac mains relay fuse blown
      Not writing to disk

BNC PB-4
      Amplitude 90,000
      x5 attenuator IN
      t_r 100ns tau_d 50us
      - polarity
      frequency range 25Hz
      delay MIN, tail pulse, INT ref

ASIC settings 2017Oct23-14.38.03
      *all* FEE64s slow comparators 0xa

Detector biases & leakage currents OK - see attachments 1 & 2
      *all* system wide checks OK *except* nnaida21 fails ADC calibration
      Ambient temperature +24.3 deg C, d.p. +8.7 deg C, RH 37.1%

02.54 Replace 250V/16A fuse and power up

FEE64 Temperatures OK - see attachment 3
      good events statistics stable & OK - see attachments 4

03:30 Stats with nnaida13 slow comparator threshold raised to 140keV - Attachment 5

03:50 Pulser widths done, slow comparator threshold raised to 0xc ~120keV for  nnaida 19-22
      Statistics - Attachment 6

05:40 Beam now going into F11. Wasabi and YSol in front of AIDA
      AIDA is seeing light particles
      Waveforms look good
      Layout 7 - Attachment 7
      layout 8 - Attachment 8
      Statistics with light particles going through - Attachment 9
      Bias and leakage currents ok - Attachment 10

We are taking the light ion data to file in R17_*

06:50 Light ion data continues
      System wide checks all ok

07:22 Bias and leakage ok - Attachment 11
      FEE Temperatures ok - Attachment 12
      Stats - Attachment 13

08:15 Light ions stop still writing file

08:27 Beam into aida run R17_30
      Zero degrader, just 4mm of WAS3ABI
      WAS3ABI run 120
      BRIKEN started run at 08:27 run 18
      BIGRIPS Run 8
      Timestamp reset at 08:27
      Stats with beam - Attachment 14

08:44 Waveforms with implants in the detector
      Layout 7 - Attachments 15 & 16
      Layout 8 - Attachments 17 & 18
      Layout 1  linear and log attachments 19 & 20 
      Leakage and bias ok - Attachment 21

09:14 Just noticed the stats in nnaida13 has dropped rate. Noise source may have been turned off
      Statistics - Attachment 22

Spectra from the 0mm degrader run - Attachments 22-27

09:20 BRIKEN and WAS3ABI stop on run 162 aida on R17_35
      1mm degrader moved in
      BigRIPS on run 9
      BRIKEN run 19
      WAS3ABI start on 163
      AIDA on R17_35

Rates similar to last screenshot of stats 09:14

09:26 Leakage and bias ok - Attachment 28

09:41 Beam stops
      AIDA on file R17_37
      BRIKEN stops running
      WAS3ABI on run 178
