Experimental verification of the applicability of a new method for improving polarizing neutron coatings

A new method for improving polarizing neutron coatings has been verified experimentally. This method is based on the use of Ti interlayers with a negative potential (“antibarrier layers”) at interfacial layers of a polarizing coating for suppressing reflections of neutrons with the undesired spin. It can be expected that the further development of the method will lead to the creation of polarizing neutron supermirrors and multilayer monochromators of a new generation with flipping ratios up to 103. The neutron optics based on these superpolarizing coatings not only will improve the performance and thus extend the range of applications of polarizing devices but also can be the basis for the design of novel neutron instrumentation.
