Perspectives for photorefractive materials in neutron physics — •Romano Rupp1, Martin Fally1, Jürgen Klepp1, Christian Pruner2, Yasuo Tomita3, and Irena Drevensek41Univ. Wien, Austria — 2Univ.

The phenomenon where light irradiation changes the refractive index is called a photorefractive effect. There are several mechanisms that may result in neutron photorefraction. For example, all photoconductive isolators have in principle the potential to exhibit neutron photorefraction. Particularly strong effects appear in piezoelectric materials, mixed electronic-ionic conductors or materials close to, e.g., a ferroelectric phase transition. We report on neutron diffraction from holographic gratings induced by light irradiation, neutron-induced holographic grating decay, and investigations on light-sensitive dielectrics and nanoparticle composites for applications in neutron physics.
