(2012) A dynamically adjustable wavelength-sensitive neutron filter. Nuclear Instruments and Methods A, 677. pp. 1-3. ISSN 0168-9002Full text not available from this repository.
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.
