NEUTRON POLARIZATION EQUIPMENT

摘要

A neutron polarization apparatus is provided that provides a neutron beam polarized by an interaction between a spin of a neutron in an incident neutron beam and a magnetic field. The apparatus includes a quadrupole magnet (2) disposed around a passage of a neutron beam, a tubular neutron absorber (3) provided in the quadrupole magnet (2) along am axial direction of the neutron beam, and a solenoid coil (4) disposed at an exit of the quadrupole magnet (2), adiabatically coupling the quadrupole magnetic field produced by the quadrupole magnet (2) and applying a bipolar magnetic field. The neutron polarization apparatus can polarize a neutron with a high polarization unavailable in the prior art.
