Full-fledged neutronic study on neutron sources at an accelerator driven neutron source was started at Hokkaido University in Japan. The methane cold moderator was firstly developed and then a quasi-elastic spectrometer was constructed. They were transferred to KEK neutron source, KENS. After then, by using the Hokkaido University neutron source (HUNS), we developed for J-PARC a coupled hydrogen moderator that is the most efficient cold moderator. The pulsed neutron imaging is one of unique experiments. Owing to a compact neutron source with the cooperative use of the large facilities the pulsed neutron imaging has been developed and expanding its application fields, which lead to the imaging instrument RADEN.
