16:04  DAQ continues running OK
       All system-wide checks OK except nnaida7 ADC calibration fails
       FEE64 temperatures OK - attach 1
       Merger and Tape Server OK - see attach 2 & 3

16:30 DTAS and BigRIPS stop
      AIDA on file R2_406

16:35 Beam stop.
      AIDA plastic gain increased by a factor 2
      Moved the lead bricks between AIDA and F11, 1 cm further away to the sides

      Chiller water level OK
      Humidity  34.6%
      Temperature 23.4 C
      Dew point 7.1 C
      

16:40 Beam restart
      AIDA run R2_408
      DTAS 70 (from DTAS ELOG)
      BigRIPS 2030  (from DTAS ELOG)

      No obvious changes to the implantation pattern. May need more stats.   

      Detector leakage current OK - see attach 4    

17.31 nnaida14 3.*.H & 4.*.H spectra - attachments 5 & 6

      Corresponds to RHS DSSSD#3 - decrease in rate observed but no evidence of systematic variation of HEC energy 

      Modified implantdecay4.f to select events with x & y energy > ADC ch 1600 (c. 1MeV) to observe x-y hit pattern
      of light particles - see attachments 7 & 8
      Low stats but light particle distribution appears to be symmetric with no obvious RHS cut


17:37 DTAS & BigRIPS DAQ stop
      Beam stop
      Lead moved back as before
      AIDA plastic gain decreased by a factor 5

17:40 DTAS and BigRIPS stop

18:43 DAQ continues OK
      All system wide checks OK - except nnaida7 fails ADC calibration as usual
      FEE64 temperature OK - see attach 9
      Stats OK - see attach 10
      Merger & Tape Server OK - see attach 11 & 12
      Leakage currents OK - see attach 13
      HEC & LEC events plots attached - attach 14 & 15 - note LEC in DSSD#3 are > 3 MeV only (light particle-like)

21:15 Beam is back - briefly
      AIDA R2_446

21:17 Beam lost - operators advise "this will take a long time"

22:16 Beam is back!
      AIDA R2_454

      System-wide checks as usual

      DTAS reports rate in F11 down by 20%, and rate in AIDA plastic sees similar drop.
