Abstract

Characteristics of a neutron focusing device based on five thin-film multilayers that are (1) oriented at slightly different angles with respect to the mean ray to converge the neutron beam reflected by each individual section, (2) have slightly different d-spacings such that the neutron beam reflected by each section has the same mean wavelength, were evaluated using a Monte Carlo program for a number of geometries. The influence of changing the distance between the focusing device and the detector was studied,and the effect of small deviations from the desired values was also explored.
