Comparison of polarizers for neutron radiography

Abstract

Imaging with polarized neutrons is a new method to measure the spatially resolved magnetisation. It is based on the interaction of a polarized neutron beam with magnetic fields. In this paper we present an overview of different polarizing techniques and their application for neutron imaging. The performance of various setups is discussed. It is demonstrated that radiography with polarized neutrons may evolve into an important technique for determining the homogeneity of ferromagnetic samples. © 2010 IOP Publishing Ltd.
