τSPECT aims to measure the lifetime of free neutrons. This lifetime factors into the CKM-Matrix and thus a precise measurement allows for a test of the standard model as well as conclusions regarding the genesis of matter. To eliminate losses during the storage due to neutron capture in materials, a full magnetic storage is set up. The longitudinal magnetic reservoir field is provided by super conducting magnets previously used in the aSPECT experiment and several added correction coils. Radial magnetic storage is realized with a permanent magnet multipole Halbach array. So far neutrons with radial kinetic energies of up to roughly 60neV are projected to be storable. On this poster the multipole-array and its storage capabilities for ultra-cold neutrons will be presented.
