Just after completing the installation of the TOP Detector
On May 11th, all modules of the TOP Detector were installed.
The TOP Detector is part of the cylindrical barrel of the Belle II detector. It is a newly built detector for precision identification of pi and K mesons.
The TOP detector system consists of 16 modules. Each module contains finely polished quartz, MCP-PMT (Micro Channel Plate Photo Multiplier Tube) photo-detectors, and high-speed readout electronics.
The TOP detector system is being built by an international collaboration of researchers from Japan, the US, Italy and Slovenia. The mechanical installation of the 16 modules was done by a team from Nagoya University and KEK.
