Pioneer is a single-crystal neutron diffractometer optimized for small-volume samples and weak signals at the Second Target Station Oak Ridge National Laboratory. This paper presents preliminary optical design progress, focusing on rationale behind key choices. It covers T0 bandwidth disk choppers, guide beam control system, incident-beam polarizer, scattering collimators, additional strategies. The chopper locations are selected to maximize transport while taking advantage of standardized...
The Quite Intense Kinetics Reflectometer (QIKR) will be a general-purpose, horizontal-sample-surface neutron reflectometer. Reflectometers measure the proportion of an incident probe beam reflected from surface as function wavevector (momentum) transfer to infer distribution and composition matter near interface. unique scattering properties neutrons make this technique especially useful in study soft matter, biomaterials, materials used energy storage. Exploiting increased brilliance...
For the three macromolecular crystallography beamlines of Swiss Light Source, a new unified diffractometer – D3 was developed. We present details engineering and implementation project components that were fabricated in-house by design facilities Paul Scherrer Institute (PSI). Key custom designed at PSI including microspectrophotometer for sample viewing optical spectros-copy combined Köhler spectroscopic illumination lamp. In addition, all elements beam steering shaping such as an exposure...
