... and the development of eventmode neutron detection, which will greatly increase experimental throughput, enable instruments to collect data while the instrument is moving, and provide tools to study time-dependent phenomena. MACS is losing its leading-edge because of the development of competing capabilities at both spallation-based and reactor-based neutron sources around the world -- for example, instruments at the Spallation Neutron Source, Paul Scherrer Institute, and the European Spallation Source (ESS)

... Opportunities and Challenges Introduction of Wolter optics to the NeXT instrument in coming years will enable improved time and spatial resolution, permitting more detailed exploitation of more complex sample environments. The neutron phase-imaging option on this instrument provides enhanced sensitivity to structural thickness and other structural properties by more than an order of magnitude.

... NIST actively seeks outside resources to support software development through joint development projects with other facilities and through direct government funding. Refl1D, the NCNR reflectometry program, was initially developed under the DANSE (Distributed Data Analysis for Neutron Scattering Experiments)

... instrument, scheduled to be fully operational in 2019, has a novel reflectometer design for reactor sources that involves the delivery of multiple streams of neutrons with different wavelengths onto the sample at the same area using an array of monochromators. A single CANDOR detector array consist of 54 highly oriented pyrolytic graphite crystals set at different takeoff angles to diffract neutrons into 6 LiF:ZnS(Ag)
