Neutron diffraction from commercially available Bayfol photopolymer film gratings
We use materials that are sensitive to light combined with holographic techniques to develop diffraction gratings for long-wavelength neutron optics. After holographic exposure, the treated materials exhibit a periodic neutron refractive-index pattern, arising from a light-induced redistribution of the constituents. Our goal is to find the most versatile and efficient material to produce neutron-optical elements, such as wavelength-standards and gratings for neutron phase-imaging or very-cold neutron (VCN) interferometry. The experiment proposed here aims at testing diffraction gratings based on commercially available light-sensitive photopolymer films routinely used to produce phase holograms for light optics.
