It's a new day, it's a new log entry !!

01:25 DTAS run 46 started
      BigRIPS run 2019
      AIDA run R2_268

DAQ running smoothly
      No change in Stat and Rate (stat zeroed at the beginning of this DTAS run)- See attachment 1
      Merger rate: 630k item/sec - See Attachment 2
      TapeServer rate still ~5 Mbytes/sec - See attachment 3
      
      Temperature and HV ok - See attachment 5 & 6

System-wide checks OK except nnaida7 fails ADC calibration as usual.

!!!
      Victor said that the run AIDA R2_249 is missing in the correlation merge data. This is the run when the
      correlation scaler was reset (as DTAS was running out of range in some of their timing histograms) (See
      elog end of Sunday)
      !!!

02:23 Rate in DSSD#3 card 9 and 12 slowly reaching 100kHz while 14 and 15 ~ 50kHz. See attachment 7
      TapeServer rate ~ 5.5 kHz

03:25 Change of DTAS run:
      DTAS run 49 started
      BigRIPS run 2020
      AIDA run R2_286

Experiment still running smoothly. No significant change since last comments 2h ago.
      Leakage current in detector 3 is increasing slowly see attachment 8 & 9

05:25 Change of DTAS run:
      Note: DTAS run stopped during AIDA R2_305 and re-started during R2_306.

DTAS run 52 started
      BigRIPS run 2021
      AIDA run R2_306

Pretty quiet night shift.
      Stat & Rate in attachment 10 - DSSD#3 FEE card 9 back down to 60kHz
      Merger rate: 650k item/sec - See attachment 11
      TapeServer rate still ~5.1 Mbytes/sec - See attachment 12

System-wide checks OK except nnaida7 fails ADC calibration as usual.
      
      X vs Y HEC spectrum in attachment 13
      LEC E vs HEC-LEC spectrum in attachment 14
      Both spectra zeroed

Bias in attachment 15
      Temperature unchanged
