[QC on FLP - plot integrated over the run] Raw Data Error#

Green: good quality Red: bad quality
ErrorTypeOK ErrorTypeError
  • If no entries, a green message "No Error: OK" inform you that everything is working properly.
  • In case of errors, a red message will appear: call EMCAL oncall if EMCAL is included in global runs. Take note of the error-type in the y axis.

[QC on FLP - plot integrated over the run] Payload Size/events#

good quality bad quality empty
PayloadSizeEvOK PLEvError PLEvempty
  • If "Data OK" is shown, everything is fine.
  • If some of the DDL presents entries that are larger than the others, a red message will appears: please call EMCAL oncall.
  • If the plot is empty, and EMCAL is included in the data taking, call EMCAL oncall.

[QC on FLP - plot integrated over the run] Bunch minimum amplitude EMCAL+DCAL#

good quality bad quality empty
BunchOK BunchError BunchEmpty
  • One peak should be visibile if EMCAL is in data taking.
  • If a second peak appears around "Min raw amplitude (ADC)" in the range 20-50, call EMCAL oncall
  • If the plot is empty, and EMCAL is included in the data taking: please call EMCAL oncall

[QC on EPN - plot integrated over the run] Cell Occupancy plots (PHYS) for E>0.2 GeV and E<0.2 GeV and Cell Occupancy plots (CALIB) for E>0.5 GeV#

IF PHYSICS RUN - The occupancy plots should be uniformly filled during Physics runs.
- if something noisy appears, please call the EMCAL oncall. - If the plot is empty, and EMCAL is included in the data taking, call EMCAL oncall.

In case counts in a certain detector segment stop increasing the corresponding segment stops sending data. The corresponding area must be visible in both plots. - call EMCAL on-call

  • no instructions for the moment.
  • If the plot is empty, and EMCAL is included in the data taking, call EMCAL oncall.

  • We expect a gaussian peak roughly centred at 0 and a structure of single lines with a spacing of 100 ns from noisy channels. Depending on the filling scheme smaller gaussian like peaks from from pileup could appear. In such cases the data is OK.
  • In case a second peak appears which is either of the same magnitude as the main peak or of magnitude 1/3 as the main peak and the peaks are separated by 100 ns call the EMCAL on-call
  • If the main peak deviates from 0 by more than 100 ns call the EMCAL on-call
  • If no gaussian like peak is present call the EMCAL on-call
  • If the plot is empty, and EMCAL is included in the data taking, call EMCAL on-call.

Number of triggers#

DigitTimeOK DigitTime
The number of physics triggers must increase while the run is ongoing. In case the number of trigger stays constant no data is received any more from the detector (most likely detector busy) - call the EMCAL on-call.
