Abstract
We report progress towards magnetic trapping: of ultra-cold neutrons (UCN) in preparation for a neutron lifetime measurement. UCN will be produced by inelastic scattering of cold (0.89 nm) neutrons in a reservoir of superflui d He-4 and confined in a three-dimensional magnetic trap. As the trapped ne utrons decay, recoil electrons will generate scintillations in the liquid H e, which should be detectable with nearly 100% efficiency. This direct meas ure of the number of UCN decays vs, time can be used to determine the neutr on beta-decay lifetime. (C) 2000 Elsevier Science B.V. All rights reserved.
