The design, performance, philosophy, lessons learned and advantages of the neutron total scattering spectrometer for hydrogenous materials, FAST, under consideration for the J-PARC-JSNS, are described. In particular, novel instrumentation concept such as the small fractional scattered neutron flight path, = L/(L+L), where L is the incident flight path, moderator to sample, L is the scattered neutron flight path from sample to detector, is presented and their expected performance at the JSNS is considered.

In this research report we describe the design of DYANA, a new neutron spectrometer dedicated for biology, biomaterials, and related soft-matter studies, which will be installed in the material and life science experimental facility project at the JAERI Tokai establishment. The DYANA spectrometer is an indirect-geometry crystal-analyzer instrument and it's energy and momentum transfer range are from several 10eV to several meV and from 0.1 to several , respectively. These specifications will become possible to do the study of protein dynamics analysis.
