Title: Small-Angle Scattering at the ISIS Neutron Source

Abstract:

The ISIS Pulsed Neutron & Muon Source, located about an hour to the west of London, United Kingdom, is home to one of the largest and most productive collections of Small-Angle Neutron Scattering (SANS) instruments anywhere in the world. But ISIS is also a spallation neutron source, not unlike the SNS or J-PARC, meaning that SANS is performed using time-of-flight techniques. These confer a number of experimental advantages over SANS at traditional reactor-based sources, such as providing a very wide dynamic range in Q (Qmax/Qmin > 300), excellent wavelength resolution (typically 3 – 8%), better Q-resolution over more of the Q-range and, usefully, allows trade-offs between statistics and Q-resolution to be made post-experiment. In this presentation we shall give an overview of ISIS, our SANS instrument suite, and our capabilities, illustrated by some scientific examples.
