Abstract
The possibility of focusing neutrons from a pulsed source into a narrow velocity interval is investigated. In particular the development of a polarized neutron pulse in a traveling fixed width and in an expanding magnetic oscillator potential is described. Expressions are derived for obtainable intensity gain and monochromaticity. In a comparison the feasibility of both systems as active monochromators with up to several orders of magnitude intensity gain over a wide wavelength regime is pointed out. Some further applications of traveling magnetic potentials in neutron optics for beam freezing and focusing in space are discussed too. Finally a quantum mechanical treatment is given showing the general validity of the results.
