FIT-FT0

FT0: 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.

FT0: 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 Vertex trigger.

Actions:
- If ERROR - call FIT-on-call.
- If WARNING - compare to FV0 and FDD BC-trigger plots; if they also show WARNING - call FIT-on-call.

FT0: Fraction of events with CFD in ADC gate

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

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.

FT0: 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 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.

FT0: Fraction of channels out of colliding BCs

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

Fraction of channles fired out of colliding BCs. Horizontal lines show the levels below which the warnings/errors are raised.

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

FT0: Validation of hardware (HW) triggers in software (SW)

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

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.
