Abstract
The present calculations describing the Bonse-Hart Ultra-Small-Angle Neutron Scattering (USANS) Instrument with triple-bounce Si channel-cut crystals show that significant gains in neutron flux and Q-resolution can be achieved using multiple high-order Bragg reflections. These reflections become usable only after combining the Bonse-Hart and Time-of-Flight techniques, thus this variant of the USANS camera needs a pulsed neutron source. We clearly demonstrate that new instruments of that type installed at the SNS water moderator will improve the current state-of-the-art USANS camera dramatically increasing the neutron flux and sharpening the Q-resolution by almost one order of magnitude.
