FIT-FV0#
FV0: General#
All QC plots are generated in 5 min. cycles. The histogram contents are reseted after each cycle.
Please wait at least 10 min. from the start of the RUN to judge about the quality of collected data.
FV0: Out of bunch collisions#
[QC on EPN/QC nodes - plot integrated over the QC cycle]
BC vs trigger correlation for the events which were detected but are not aligned (out-of-bunch) with LHC filling scheme. The number of out-of-bunch events depends on the trigger settings. The check is performed for the TrgNchan trigger.
Actions:
- If ERROR - call FIT-on-call.
- If WARNING - compare to FT0 and FDD BC-trigger plots; if they also show WARNING - call FIT-on-call.
FV0: Fraction of events with CFD in ADC gate#
[QC on EPN/QC nodes - plot integrated over the QC cycle]
Efficiency for getting charge information in each detector channel. Horizontal lines show the levels below which the warnings/errors are raised.
Actions:
- If WARNING - no action.
- If ERROR - call FIT-on-call.
FV0: Fraction of events with the CFD in time gate#
[QC on EPN/QC nodes - plot integrated over the QC cycle]
Fraction of events with CFD in gate in each detector channel. Horizontal lines show the levels below which the warnings/errors are raised.
Actions:
- If WARNING - no action.
- If ERROR - call FIT-on-call.
