SANS at Pulsed Neutron Sources: Present & Future Prospects

R K Heenan, J Penfold & S M King

J. Appl. Cryst., (1997), 30, 1140-1147

(This paper is the best in print description of LOQ and TOF-SANS)


Small-Angle Neutron Scattering

S M King

Chapter 7 in Modern Techniques for Polymer Characterisation

Pethrick & Dawkins (editors), Wiley, (1999)

(ISBN 0-471-96097-7)

(This chapter is an accessible and readable account of how to conduct SANS experiments and analyse the data. Though it focuses on polymeric samples, the techniques and principles are extendable to any type of sample)

If you are writing a paper incorporating LOQ data, you might like to include the following text and references in your experimental section:

Small-Angle Neutron Scattering. SANS data were obtained on the LOQ small-angle diffractometer at the ISIS Pulsed Neutron Source (STFC Rutherford Appleton Laboratory, Didcot, U.K.).[a,b] This is a fixed-geometry “white beam” time-of-flight instrument which utilizes neutrons with wavelengths, λ, between 0.2 and 1 nm. Data are simultaneously recorded on two, two-dimensional, position-sensitive, neutron detectors, to provide a simultaneous Q range of 0.08−16 nm-1. Each sample and background was placed in x mm path length quartz cuvettes and was measured for a total of x h in order to gather data of high statistical precision. Each raw scattering data set was then corrected for the detector efficiencies, sample transmission and background scattering and converted to scattering cross-section data (∂Σ/∂Ω vs Q) using the instrument-specific software.[c] These data were placed on an absolute scale (cm-1) using the scattering from a standard sample (a solid blend of hydrogenous and perdeuterated polystyrene) in accordance with established procedures.[d]
