The prototype of a wavelength-sensitive neutron filter has been realized and tested successfully for the first time. The filter exploits the neutron wavelength dependence of the transparency of He-3 gas. The analysis of test results gives high wavelength resolution Delta lambda/lambda similar or equal to 0.5% over the broad wavelength range 0.2-5.2 angstrom. We propose an idea to expand the filter range in the short wavelength direction by use of a cryogenic environment, and also consider the use of media using other than He-3 gas. The proposed filter might be used in advanced reflectometers and SANS2D neutron scattering instruments. (C) 2012 Elsevier B.V. All rights reserved.
