a neutron polarizing cavity using double a polarizing neutron mirror

摘要

PURPOSE: A NEUTRON POLARIZING CAVITY USING DOUBLE A POLARIZING NEUTRON MIRROR is provided to obtain high polarizability through a polarized neutron mirror without increasing the length of a polar machine according to the arrangement of a polarized neutron mirror. CONSTITUTION: A body(10) forms a vacuum space therein where a neutron is transferred. The neutron mirror is comprised of a double layers structure of a titanium thin film and a nickel thin film which have various thicknesses. A plurality of polarizing members(20) are formed within the body. A plurality of polarizing members is arranged along the neutron wavelength by a regular interval. The folding angle of the polarizing members is formed with corresponding to the wavelength of the neutron beam entering the body.
