Abstract

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 ³He gas. The analysis of test results gives high wavelength resolution Δλ/λ≃0. 5% over the broad wavelength range 0.2-5.2 . 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 ³He gas. The proposed filter might be used in advanced reflectometers and SANS2D neutron scattering instruments.
