The Time-Of-Propagation (TOP) counter is a novel ring-imaging
Cherenkov detector that primarily consists of a quartz bar radiator,
micro-channel plate photomultipliers and front-end readout
electronics. These TOP counters are installed in the central region of
the Belle II detector to provide the crucial information on charged
particle identification (PID).
Here we present an overview of PID studies in Belle II, with a focus
on the performance of the TOP detector. The results presented are from
the most recent data recorded and show reasonable agreement with
expectations based on simulation studies.

TIPP2020 abstract resubmission? No, this is an entirely new submission.
