09:33 DAQ still running, file R4_11. 
      Bias/leakage ok (attachment 1)

      Leakage currents whilst still acceptable are up around 400nA on yesterday
      Have checked all detectors and rates and pulser peak widths are still good across the board
      Will keep an eye on but for now it appears to be ok
      BRIKEN is currently doing a Cf source test so could be a result of charging from the source

      Humidity: 33.1, Temperature: 24.6, Dew point: 7.1
      FEE temperatures ok (attachment 2)

09:38 System wide checks ok

10:25 Pulser peak widths all checked
      Widths comparable to 26th apart from 24 which is much wider from ~70 -> ~120
      Waveforms, layout 7 and 8 - attachments 3 and 4

10:37 Started new run on file R5 at time 10:37
      Threshold changed back to 100 from 10
      Pulser on at 2Hz

16:34 Stopped R5 alpha run
      Lowered thresholds to 0xa to produce higher rate data to test AIDA<->BRIKEN synchronisation
      Started file R6 to do this
      DAQ crashed on start ASIC readout with unable to connect to nnaida19 message appearing.
      Could not clear despite attempts at restarting the merge if that was the cause.

      FEE power cycle

17:03 DAQ recovered, R7 started
      AIDA did not crash
      BRIKEN started Ge fill cycle
      AIDA did not crash during or after

17:17 R7 Stopped sync program is being worked on by Jorge,

17:32 Thresholds raised back to 100 from 10
      Pulser switched off
      R8 started
      leakage current dropping down (attachment 5)
