Abstract

The DNA is a near-backscattering instrument that will be installed at the J-PARC neutron facility. Several kinds of analyzer crystals are planned to be installed in it and include PG(0 0 2), Ge(3 1 1), Si(1 1 1) and Si(3 1 1). The Si analyzers will use perfect crystals. Conversely, with the PG and the Ge analyzers, the plan is to utilize mosaic crystals. We have examined the reflecting intensities and mosaic spreads of hot-pressed and as-cut Ge and PG crystals of several qualities using neutron scattering measurements.
