Abstract

In this paper is described several types of velocity-dependent spin-flippers and their application in the scheme of magnetic monochromator of polarized neutrons designed at the Petersburg Nuclear Physics Institute. Efficiency of the magnetic monochromator is comparable with the best types of crystal monochromators and mechanical selectors but only the magnetic monochromator makes it possible to variate the wavelength, the width and the shape of thermal neutrons spectrum in the wide range without changing the geometry and the cinematic of the device. Up to now, development of this perspective method of monochromatization is limited by a 'background problem' connected with the presence of non- monochromatic neutrons produced by the polarizing elements of the device. It is shown that this problem is solvable and possible solutions are discussed.
