| Outline of Final Research Achievements |
The Super KEKB accelerator started it operation in Feb. 2016. In the Belle II experiment that uses Super KEKB a particle identification detector plays an important role to extract expected physics performance. In this research program we developed a Ring Imaging Chrenkov detector (A-RICH) in which silica aerogel tiles are used for radiators and HAPDs as photon detectors aiming to get a 4 σ pion/kaon separation. A prototype test using an electron beam reveals that it has enough performance as expected. Currently every elements to construct the real A-RICH detector such as aerogel tiles, HAPDs, readout electronics with ASICs, high voltage power supplies, a monitor system with optical fibers are ready for installation and we will start construction soon
