Abstract

The design of a new permanent-magnet trap for ultracold neutron storage in an experiment on determining the neutron lifetime is presented. Particular attention is paid in this new trap design to the neutron confinement system. Optimization of this system provides an opportunity to raise the strength of the confinement magnetic field and thus increase considerably the number of neutrons stored within the trap and the statistical accuracy of neutron lifetime measurements.
