Electronic and Software Support of a Test Time-of-Flight Meter for Neutron Spectra

Abstract

A description of the operation and functional units of a test time-of-flight meter for neutron spectra for a polarized neutron reflectometer that will be installed after the neutron cold source of the IR-8 reactor neutron guide is presented. The developed electronic and software support allows measurement of the neutron transit time and, accordingly, the determination of the spectral characteristics of a neutron beam, as well as controlling the exact spatial positions of a chopper disk, diaphragm, and ³He-detector using stepper motors and controllers.
