Compound Magnetic Lens for Providing Focused, Polarized Neutrons

An improved neutron collection and focusing lens is needed for small angle neutron scatter and neutron microscopy, and increasing flux for thermal neutron capture gamma analysis. Adelphi Technology proposes to design, fabricate, and test a two-dimensional magnetic lens to refract and focus thermal and cold neutrons. The proposed magnetic lens is comprised of a stack of annular permanent magnets, which are radial magnetized and alternate in polarity in the radial direction. Commercial Applications and Other Benefits: The proposed magnetic neutron lens will provide neutron focusing and imaging for neutron microscopy, small angle neutron scatter, and other neutron optics applications. The sales of the magnetic lens are government and academic neutron facilities, which serve and promote industrial and technological development in the U.S. The proposed lenses provide an important indirect benefit to the U.S. economy by enhancement of neutron-based R & amp;D facilities.
