Abstract

A comparative analysis of neutron polarizers of three types (bender, S-shaped bender and wedge-shaped polarizer) most suitable for operating on small-angle diffractometers is carried out. A wedge-shaped polarizer is shown to be preferable for a small-angle diffractometer. With the specified parameters of the working area (a polarizing supermirror), the geometric parameters of the polarizer are determined, which are optimal for a small-angle instrument.
