aSPECT magnet

UCN are stored in tSPECT using magnetic storage. This is based on the Stern-Gerlach force that a particle with a magnetic moment, like then neutron, experiences in a magnetic gradient field. At tSPECT the gradient of the magnetic bottle is formed by the superconducting magnet system of the aSPECT experiment in axial direction and a magnetic multipole inserted into the bore of the aSPECT cryostat for the radial direction.
