| Outline of Final Research Achievements |
The study of the Extreme Universe with high energy gamma rays has been carried out using the MAGIC telescopes and the Fermi gamma ray satellite. Many topics, the Origin of high energy cosmic rays, pulsed gamma ray emission from pulsars, high energy phenomena around super massive black holes, Extragalactic Background Light using the absorption of gamma rays from distant Active Galactic Nuclei, Dark Matter annihilation in dwarf galaxies have been studied extensively. For the further development of high energy gamma ray astronomy, we have promoted the development and research work for the 23m diameter CTA Large Size Telescope (LST) within the framework of an international collaboration where the major countries are Japan, Germany, Spain, Italy and France. We have started the construction of the first LST in summer 2016, and will complete it in FY 2017.Japan has responsibilities on the design, development and production of segmented mirrors, actuators and active mirror control system, and also photo-sensors, HVs, pre-amplifiers, GHz sampling readout electronics. We have finished mass production of the photo-sensors and shipped them to La Palma. We are now waiting to install them after the construction of the telescope structure. We are aiming to have the first light with the first LST in 2017.
