14.15 BigRIPS run number is now 1029

15.22 BigRIPS run number is now 1030

15.36 DSSSD bias & leakage currents OK - see attachments 1 & 2
      FEE64 temperatures OK - see attachment 3

DAQ continues (RIBF03R1/R20)

Degrader 3mm Pb fixed + (0.3mm W/1mm Al + 0.5mm W/1mm Al) variable
      
      ASIC settings 2016Nov17-10.50.10

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

15.43 System-wide checks OK *except* clock status errors from amongst nnaida5, 7, 8, 15 & 16 - bit 2 always set

15.46 Visual scalers - see attachment 4

16.04 Accelerator group wants to change the carbon stripper foil -- beam stop
      Run stop (R20_27 at the end)

16.10 Ambient temperature +25.2 deg C, d.p. +2.6 deg C, RH 23.8%

16.17 BigRIPS run 1031 is junk

16:17 Added 1 mm Al plate to the front of the 3 mm Pb degrader (on the upstream side of PE wall)
      Pb bricks stacked between MUSIC1 and MUSIC2.  
        Not enough time to measure it because of quick foil change
        Basically, about 10 cm thick, and it has a ~7 cm +/- 1 mm window in X, and no cut in Y (it is above and
below MUSIC window)

16:19 Start AIDA run R21.  BRIKEN run started.  BRIKEN Sync issued.

16.22 BigRIPS run 1032

16.26 SyncCheck - see attachment 5

17:01 AIDA merger stopped.  When attempting to stop the Run, the following error is issued:

STATE for nnaida1 returned with an error
error: SOAP http transport timed out after 20000 ms
NONE
error: SOAP http transport timed out after 20000 ms
    while executing
"$transport $procVarName $url $req"
    (procedure "::SOAP::invoke" line 18)
    invoked from within
"::SOAP::invoke ::SOAP::_DataAcquisitionControlClient__GetState"
    ("eval" body line 1)
    invoked from within
"eval ::SOAP::invoke ::SOAP::_DataAcquisitionControlClient__GetState $args"
    (procedure "DataAcquisitionControlClient__GetState" line 1)
    invoked from within
"DataAcquisitionControlClient__GetState"

Going through hardware checks, the check sync errors since baseline gets 23/24 failures  (nnaida6 is still my friend)
      Perform TimeStamp RESYNC -> all can pass the check

17:17 AIDA looks happy now.  R22 started.

18.16 System-wide checks OK *except* clock status errors from amongst nnaida5, 7, 8, 15 & 16 - bit 2 always set
      and ADC calibration fails nnaida13

18.27 DAQ stops OK
      Soft reset following LN2 refill cycle

21:11 BRIKEN DAQ was not working properly from the last ~half hour (unrelated to AIDA), and had to be restarted and we
also had to send a couple of synchronization pulses.

R25_0: Started new run once BRIKEN was running and all DAQs synchronized
