Construction of Ibaraki prefectural neutron spectrometers

Ibaraki Prefectural Government established Science Frontier 21 Initiative (SF21) in 2001. In SF21 the active co-operations between Tsukuba, Tokai and Hitachi areas are accelerated and two Prefectureʹs neutron spectrometers have been constructed in order to establish the advanced industrial zone by setting the J-PARC as a key component. In addition, the industrial applications of neutron will be promoted. The objectives of SF21 are promotion of industrial applications of J-PARC, grow-up of neutron research scientists, and establishment of infrastructure supporting international collaboration. In this paper, outline of the two Ibaraki prefectureʹs spectrometers are described.
