<title>Neutron multilayer structures for fundamental experiments in UCN optics</title>

Abstract: The experience in manufacturing and testing of neutron multilayer structures, interference filters, is described.Construction of a gravity UCN spectrometer based on the use of such devices is also reported. Some results of the test experiment of the UCN dispersion law performed with such a spectrometer are presented. Among them are the resonant mode mixing effect due to scattering by the roughness. Some possibilities of new experiments based on a similar method are investigated.

“…Neutron Fabry-Perot interferometers (FPI) also referred as neutron interference filters (NIF) as well as more complex multilayered structures were many times used for the UCN spectrometry [30][31][32][33][34][35][36][37][38][39][40][41]. In context of the device to be discussed in the present paper they also play an important role.…”

“…3. A special filter, named "superwindow" [35,36], which transmits UCNs with energies in the range of 50-200 neV and effectively reflects neutrons with energies in the range of 200-700 neV. It is based on a M ¼2 supermirror with some added antireflection layers and is used for the suppression of the background of neutrons with energy higher than NIF barriers.…”

“…More accurate calculations are based on equations of continuity of wave functions at all the boundaries of such structure. An analytical solution for the reflection and transmission amplitudes of such an object is in [31], the problem of particle tunneling through a double-humped barrier is discussed in works [32][33][34]. The issue of the time of interaction with resonance structures is discussed in paper [29].…”
