The current knowledge of the neutron $\beta$-decay lifetime has come underscrutiny as of late due to large disagreements between recent precisemeasurements. Measurements using magnetically trapped Ultra-Cold Neutrons(UCNs) offer the possibility of storage without spurious losses which canprovide a reliable value for the neutron lifetime. The progress towardsrealizing a neutron lifetime measurement using a Ioffe-type trap made with aHalbach-type permanent octupole magnet is presented here. The experimentalprocedure extracts a gas of UCNs into vacuum, which reduces many known channelsof neutron losses, and detects the neutron decays via in-situ detection of theproduced protons.
