Investigation of the diffraction properties of holographic optical elements for cold neutrons
In order to proliferate science with cold and very cold neutrons (VCN), we work on holographic optical elements (HOE) with materials that have customized diffraction properties (tuned by thickness, period and grating strength) for the VCN wavelength range. We use photosensitive materials to record a light interference pattern acting as diffraction grating by optical holography. The light exposure of the material triggers chemical processes that result in a spatial modulation of its constituents, and hence, in a spatially modulated refractive index. The resulting HOE works as a diffraction grating also for neutrons. The HOE¿s performance for neutrons can be evaluated by measuring the angular dependence of its diffraction efficiency by SANS. In the proposed experiment, we aim to test holographic optical elements based on commercially available off-the-shelf Bayfol foils and, additionally, novel organic nanoparticle materials with VCN.
