Neutron diffraction from multilayer film gratings
We use light sensitive materials 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. The experiment proposed here aims at testing holographic multilayer diffraction gratings based on commercially available light-sensitive photopolymer films manufactured into multilayer structures. The idea of making stacks of Bayfol foils to reach the desired thickness led also to tests of multilayer structures. In such structures, there is a non light-sensitive layer sandwiched between two photopolymer layers. In the holographic recording process a structure of perfectly aligned diffraction gratings, distanced by a layer of insensitive material is produced, which exhibits rapid oscillating and beating diffraction patterns also for neutrons.
