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.

If a non-critical (i.e. expendable) QC task fails, please add a bookkeeping entry about it.

FV0: Amplitude vs channel#

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

fv0_ampl_channel

Charge amplitude distribution vs channel ID [0-47]. It should be non-empty.

Units: Charge is expressed in ADC channels.

Actions:

  • if one or more empty channels (crosscheck known-issues file) - call FIT-on-call.

FV0: Time vs channel#

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

fv0_time_channel

The time distribution vs channel ID [0-47]. It should be non-empty.

Units: Time is expressed in TDC channels, channel = 13 ps.

Actions:

  • if one or more empty channels (crosscheck known-issues file) - call FIT-on-call.
