Institute for Cosmic Ray Research
The Institute for Cosmic Ray Research (ICRR) of the University of Tokyo (東京大学宇宙線研究所 Tōkyōdaigaku Uchūsen Kenkyūjo) was established in 1976 for the study of cosmic rays.[1]
The gravitational wave studies group is currently using the TAMA 300 gravitational wave detector located at the Mitaka campus of the National Astronomical Observatory of Japan. They are also developing the Large Scale Cryogenic Gravitational Wave Telescope (LCGT). [2]
Facilities
Current projects
- Super-Kamiokande - Detection of neutrinos and search for proton decays in a large water tank[3]
- CANGAROO - Very high energy cosmic gamma ray observation by telescope. Located on the Woomera Prohibited Area in South Australia. [4]
- Tibet - Search for point sources of VHE cosmic gamma at Tibet heights
- Telescope Array - Aiming at highest energy cosmic ray physics by detecting weak light from atmosphere[5]
- Gravitational Wave Group - R & D for detection of unknown phenomena 'gravitational waves'
- SDSS - Making 3-D map of very distant galaxies with specific wide view telescopes as an international collaboration with Princeton University
- Theory Group - Theoretical studies for verifying Grand Unified Theory and early Universe
- Ashra (All-sky Survey High Resolution Air-shower detector) - The group has developed a new type of detector with wide angle high resolution aiming for monitoring optical and particle radiation from high-energy transient objects.[6] [7] The detector system was installed on the slopes of the Mauna Loa volcano at about 10,500 feet elevation in 2006 and 2007. Mauna Loa is located in the Big Island of Hawaii in the state of Hawaii. The detector system is currently operational.
