Description
The Time-Of-Propagation (TOP) counter in the Belle II experiment
is a novel device for particle identification (PID),
where a Cherenkov ring image is reconstructed based on timing information of each photon.
This can provide better performance of PID
than the PID detectors of the former Belle experiment,
while compact and low-mass detector system is realized at the same time.
We started detector construction at the beginning of 2015
and installation was successfully finished in the middle of 2016.
Commissioning of the installed detector
with laser calibration system and cosmic ray muons
is now in progress toward the physics data taking,
which shows reasonable performance of this detector.
In this presentation, processes of detector production and initial performance check
as well as status of commissioning after installation are reported.
