POLARIZATION OF A NEUTRON BEAM USING A SUPERCONDUCTOR

Based on the London theory of superconductivity and using the quasista tic approximation, we have calculated the interaction energy between a superconducting plane and a dipole which is moving toward or away fro m the plane. Using the decoupling approximation, we have investigated the displacement and the angle flipping of a neutron, when the neutron moves toward or away from the superconducting plane. The theoretical model can, in principle, be applied to construct an apparatus to polar ize the beam from a thermal neutron reactor.
