Abstract
The utility model relates to the technical field of neutron polarization, in particular to a compact superconducting neutron polarization turner, which comprises a vacuum thermostat, a superconductingdiamagnetic body assembly and a guide magnetic field assembly. The superconducting diamagnetic body assembly is arranged in the vacuum thermostat; the vacuum thermostat is used for providing a vacuumlow-temperature environment for the superconducting diamagnetic body assembly, so that the superconducting diamagnetic body assembly forms a Michael diamagnetic layer in the vacuum thermostat, the superconducting diamagnetic body assembly is combined with the guiding magnetic field assembly, and a front guiding magnetic field and a rear guiding magnetic field of the superconductor are segmented through the superconducting diamagnetic effect; the guiding magnetic field assembly is arranged on the periphery of the vacuum thermostat and used for forming two guiding magnetic fields with oppositemagnetic field directions on the two sides of the Michael diamagnetic layer, and the guiding magnetic fields are used for guiding polarization of neutrons penetrating through the guiding magnetic fields and enabling polarization of the neutrons penetrating through the Michael diamagnetic layer to turn over. When the neutron polarization turner is used for turning over polarization of neutrons, theoperation is simple, the performance is stable, and the turning efficiency is high.
