FIT-FDD#

FDD: General#

All QC plots are generated in 5 min. cycles. The histogram contents are reseted after each cycle.
Please wait at least 5 min. from the start of the RUN to judge about the quality of collected data.

FDD: Out of bunch collisions#

[QC on EPN/QC nodes - plot integrated over the QC cycle] fdd_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 Vertex trigger.

Actions:
- If ERROR - call FIT-on-call.
- If WARNING - compare to FT0 and FV0 BC-trigger plots; if they also show WARNING - call FIT-on-call.

FDD: Fraction of events with CFD in ADC gate#

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

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

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

FDD: Fraction of charge in ADC range#

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

Fraction of charge in ADC range 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.

FDD: 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.
