11.00 Detector biases and leakage currents - see attachments 1-2
  
      FEE64 temperatures - see attachment 3

DAQ ran overnight without problem - statistics - attachments 4-8

Plan for today

1) Develop AIDA external trigger output for fast LEC/MEC discriminator threshold 0x4, or lower

2) Replace non-rev B MACB with rev B MACB in master timestamp chain (NIM module #2)

16.15 Non-rev B MACB in master timestamp chain replaced with rev B MACB module

FEE64s power cycled and rebooted.

System ReSYNC'd successfully

System-wide tests 
            clock states 24/24 pass
            adc calibration 24/24 pass
            ASIC clock timestamp check 23/24 pass, nnaida19 fails
            SYNC errors not counting 23/24 pass, nnaida19 fails

N.B. We obtained the same nnaida19 errors before rpelacing non-rev B MACB *and* with FEE64
           previously installed as nnaida19

Module timestamps - see attachment 9

Master timestamp module nnaida6 - all clocks locked

Fitted ground jumpers to front and rear field plate connections on all four adaptor PCBs
      for each of DSSSD#2 - #5, i.e. DSSSD#1 - #6 now have field plate ground jumpers fitted.

See attachments 10 & 11 showing discriminator rates before and after fitting these additional
      ground jumpers (LEC/MEC fast discriminator threshold 0x4 or 0x5)

21.30 Moved extant data acquisition server options files to /MIDAS/DB/EXPERIMENT/AIDA/nnaida?/CONTENTS.BAK-030616
      Saved options for all data acquisition servers with
        TS_SYNC_PHASE = 0x3
        MACB_TRIG_MODE = 0x4
        ASIC Settings DB key 2016Jun03-21.03.42
        (all LEC/MEC fast disc settings 0x5 *except* nnaida5 & nnaida6 = 0x20)
