摘要：

We present a method to determine the trajectories of neutrons in multiple section straight-sided neutron guide systems. Nonreflecting sections can be handled, as well as reflecting sections with less than 100% reflectivity. It is also possible to trace the paths of neutrons which pass through a nonabsorbing guide surface, having been incident at an angle greater than the critical angle for reflection from the surface. Transverse displacements and angular misalignments between sections are readily included. The behaviour of systems with nonuniform illumination can be determined. The approach, as presently formulated, is limited to one lateral dimension. A number of practical examples of the use of the method are described. © 1990.
