Outline of Final Research Achievements

Recent observations have reported a cluster of events called as the hotspot in the arrival directions of ultrahigh-energy cosmic rays (UHECRs). Since the UHECRs can propagate straight even in the galactic or extragalactic magnetic field, it is expected to clarify the origin of them by measuring the arrival directions with high statistics. However, it requires the huge scale observatory due to the quite low flux of UHECRs.
For the purpose of realizing such a huge scale observatory, we have developed a fluorescence telescope with a single pixel as a low cost cosmic ray detector. In this research, we tested the performance of the low cost detector and confirmed that the detector has the expected sensitivity. We also succeeded to observe air showers of UHECR.Construction of an automatic observation system is progressing, and the examination is partially finished. From autumn of 2018, we will start regular operation.
