Martin (European Spallation Source ESS ERIC) Bentley, P. M. (European Spallation Source ESS ERIC; Uppsala University) Pappas, C. (TU Delft RST/Neutron and Positron Methods in Materials) Date 2016-10-10 Abstract Polarised neutron beams are used in disciplines as diverse as magnetism,soft matter or biology. However, most of these applications often suffer from low flux also because the existing neutron polarising methods imply the filtering of one of the spin states, with a transmission of 50% at maximum. With the purpose of using all neutrons that are usually discarded, we propose a system that splits them according to their polarisation, flips them to match the spin direction, and then focuses them at the sample. Monte Carlo (MC) simulations show that this is achievable over a wide wavelength range and with an outstanding performance at the price of a more divergent neutron beam at the sample position.
