09.58 DAQ continues OK - current file Oct18/R15_6
      alpha background run

09.20 all system wide checks OK *except*
        nnaida7 fails ADC calibration
        SYNC errors since baseline - see attachment 1 - baseline not zero'd following reboot of nnaida2 and
setup of all FEE64s yesterday
        SYNC errors OK following new baseline check

      detector biases & leakage currents OK - see attachments 2 & 3

      FEE64 temperatures OK - see attachment 4
      good event statistics OK - see attachment 5
      nnaida2 rate due to one hot channel

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

      1.8.L spectra - see attachments 8 & 9

       N.B. evidence of minimally ionising particles (presumably protons) from beam to F11 E detector
            ~10-15cm Pb bricks were placed within BRIKEN (CH2)n stack to stop heavy particles

      1.8.W spectra - see attachments 10 & 11 - trace updates for 9/12 p+n FEE64s have stopped, n+n FEE64s OK

15.54 DAQ continues - current file Oct18/R15_15
      nnaida17 good event rate c. 400kHz


15.57 FEE64 reset, setup, system wide checks
      all ASIC clocks sync'd using ReSYNC
      all spectra zero'd
      ASIC check load
      
      DAQ go - data transfer disabled

      good events statistics - attachment 12

      1.8.W spectra - see attachments 13 & 14
      changed LED threshold 7700 -> 8500 for 9/12 p+n FEE64s
