M. Popovici et al., 2-BENT-CRYSTAL TECHNIQUE IN NEUTRON SMALL-ANGLE SCATTERING, Journal of physics and chemistry of solids, 56(10), 1995, pp. 1425-1431
The design of two-bent-crystal small angle neutron scattering configur
ations is discussed. Neutron optics computations for experiment optimi
zation are presented. An arrangement implemented at the Missouri Unive
rsity Research Reactor is described. It consists of a curved pyrolytic
graphite pre-monochromator followed by two curved thin silicon wafers
diffracting from (111) and (220) planes, respectively.
