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] ft0_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. For the Vertex trigger should be almost ZERO counts.

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: CFD efficiency#

[QC on EPN/QC nodes - plot integrated over the QC cycle] ft0_cfd_efficiency

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.
