Don't call EMC expert during the night if run is not physics
[QC on FLP - plot integrated over the run] Error Type for SM (Super Module)#
| Green: good quality | Red: bad quality |
|---|---|
 |
 |
- 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] Payload Size/events#
| good quality | bad quality | empty |
|---|---|---|
 |
 |
 |
- 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 |
|---|---|---|
 |
 |
 |
- 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#
| good quality | bad quality (superMod not sending data) | bad quaity (superMod noisy) |
|---|---|---|
 |
 |
 |
Cell Occ. with E>0.2 GeV: the occupancy plots should be uniformly filled during Cosmics 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.
Cell Occupancy plots with E>0.5 GeV (CAL)
- if some large empty areas (expect for the PHOS hole, present in the example for Cell Occ. with E<0.2 GeV) appear, please call EMCAL oncall.
[QC on EPN - plot integrated over the run] Cell Amplitude#
- no instructions for the moment.
- If the plot is empty, and EMCAL is included in the data taking, call EMCAL oncall.
- If peaks appear but the text in histogram is okay, That's a problem due to bad channel. send a message to EMCAL expert via mattermost.
[QC on EPN - plot integrated over the run] Cell Time#
- If the plot is empty, and EMCAL is included in the data taking, call EMCAL oncall. If the errors appear during nigh shift:
- add a note in the logbook, don't call the on-call.
- in case LHC is preparing for collisions the on-call should be notified at "Prepare Ramp" (even during the night in this case) in case of such errors occur in a technical run before, so that the cards can be recovered before taking physics data.
