DEVICE FOR ADIABATIC RADIO FREQUENCY FLIP OF SPIN OF POLARIZED NEUTRONS Russian patent published in 2007 - IPC G21K1/00 G21K1/93 

FIELD: engineering of devices for controlling flows of particles, possible use for flipping spin of polarized neutrons.

SUBSTANCE: device contains one coil, creating alternating magnetic field, perpendicular to flight of neutrons, second coil, creating constant magnetic field, strength of which changes linearly along working area, parallel to flight of neutrons, and made in form of solenoid. First coil is composed of two symmetrically positioned one-layer coils, each one of which is made in form of one-layer spiral, opposite segments of which are bent at direct angle to spiral plane, and coils are mounted so that these segments are facing each other. Each one-layer coil is placed inside hermetic container made of dielectric material and repeating the shape of coil. Containers have apertures and air ducts for communication with air environment. Neutron duct is moved into space formed by two one-layer coils. Construction of device makes it possible to exclude presence of constant magnetic field, direction of which is perpendicular to neutrons flight direction, and creates magnetic field parallel to magnetizing field of neutron duct, resulting in prevention of depolarization of flow of polarized neutrons (intensiveness of the flow of polarized neutrons does not decrease).

EFFECT: increased efficiency.
