Experimental Setup for Methodological Research with Polarized Neutrons at the IR-8 Reactor

The results of the work on the development of an experimental setup for investigating polarized neutron methods at the IR-8 reactor are presented. A scheme for polarizing a monochromatic neutron beam and analyzing it using the Mezei spin flipper has been developed. A reflectometric scheme for measuring thin-film samples has been implemented using a beam of polarized neutrons, and the reflection coefficients of non-magnetic layers have been measured experimentally. The results obtained on the setup confirm the possibility of further implementation of several methods for studying condensed matter, including polarized neutron reflectometry, depolarization, and polarized neutron radiography. These research methods were implemented at the IR-8 reactor for the first time.
