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.

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

FDD: Amplitude vs channel#

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

fdd_ampl_channel

Charge amplitude distribution vs channel ID [0-15]. 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.

FDD: Time vs channel#

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

fdd_time_channel

The time distribution vs channel ID [0-15]. 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.

Known issues#

  • The Out of bunch collisions plot can be ignored in SYNTHETIC runs at the moment (i.e. no need to take any actions in case of not GOOD quality). The BC distribution is not simulated properly in MC and will always cause problems in this plot.
