Abstract

Neutron scattering on dynamic polarized proton targets is a rather efficient method for obtaining a high polarizing neutron beam. Here we study an optimization problem of proton targets using knowledge of behavior of electrodynamical parameters in the millimeter wave band. We have considered such problems as: (1) a high level of working material nuclear polarization of the target at low SHF-pumping power; (2) transparence of the target for neutrons; (3) optimal dimensions of the target and concentration of paramagnetic admixture in the target body. In this paper analysis and characteristic calculations of multilayer resonance electrodynamical structures have been carried out. They may be used for creation of polarized targets in millimeter wave bands. Thus, the main purpose of the investigation is the studying of fundamental properties of spin systems interfering with electromagnetic field in polarized targets with an inhomogeneous structure.
