Abstract
Two Soller type highly collimating neutron optical devices with a length of 200 mm are presented. They provide a triangular shaped beam divergence distribution with a FWHM of about 0.11∘0.11∘ (2 mrad) and a peak transmission of up to 80% for neutrons with a wavelength λ0λ0 of 5 Å. This corresponds to an improvement of more than a factor three compared to state of the art collimators. Measurements are presented which demonstrate the usefulness of these devices also for neutron radiography.
