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] fv0_bc_triggers

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] fv0_cfd_efficiency

Fraction of events with CFD in ADC 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.

FV0: Fraction of events with the CFD in time gate#

[QC on EPN/QC nodes - plot integrated over the QC cycle] fv0_cfd_gate

Fraction of events with CFD in time 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.

FV0: Validation of hardware (HW) triggers in software (SW)#

[QC on EPN/QC nodes - plot integrated over the QC cycle] fv0_cfd_gate

Fraction of only software or hardware (SW + HW) triggers. In ideal case both the FW and SW triggers or nighther of them should be present in a given event. Horizontal lines show the levels below which the warnings/errors are raised.

Actions:
- If WARNING - no action.
- If ERROR - call FIT-on-call.
