Space gravitational wave antenna DECIGO and B-DECIGO
川村 静児（Seiji KAWAMURA）
DECi-hertz Interferometer Gravitational-wave Observatory (DECIGO) is a future Japanese space gravitational-wave antenna. The most important objective of DECIGO is to detect gravitational waves coming from the inflation of the universe. DECIGO consists of four clusters of spacecraft, and each cluster consists of three spacecraft with three Fabry-Perot Michelson interferometers. As a pathfinder mission of DECIGO, B-DECIGO should be launched to demonstrate technologies necessary for DECIGO as well as to lead to fruitful multimessenger astronomy. B-DECIGO is a small-scale version of DECIGO with the sensitivity good enough to provide frequent detection of gravitational waves. In this talk, the aimed science and the mechanical and optical design of DECIGO and B-DECIGO will be explained in details.
