Many of these instruments are pushing the limits of minimum crystal size needed for neutron single-crystal diffraction, which traditionally has been a disadvantage of this method. A third-generation design is possible with even smaller pixel size. A next-generation Anger camera has already been designed, built, and tested that has a higher resolution, is insensitive to stray magnetic fields, and costs half as much to construct compared to the first generation. The Anger camera detectors 1 on several of these instruments (TOPAZ, MaNDi, SNAP, and FCD) are state of the art and designed, and originally built, in-house. New sample environments are either under active development or in commissioning for these instruments and limited polarization options have been available (e.g., FCD), but for each instrument, improvements are also ongoing for data acquisition and analysis software, and/or detectors and detector coverage. Most of these ORNL instruments, except the HFIR FCD, are still ramping up in productivity (TOPAZ, MaNDi, and IMAGINE) or are either in or just coming out of commissioning (CORELLI, SNAP for single-crystal studies, and WAND 2). ORNL has both a spallation neutron source (SNS) and a reactor neutron source (HFIR) co-located at the same site which has enabled the construction of a complete suite of single crystal diffractometers. IMAGINE in the cold-guide hall at HFIR is focused on the neutron structure determination of macromolecules. At the High Flux Isotope Reactor (HFIR), there are Wide-Angle Neutron Diffractometer squared (WAND 2), a dual-purpose powder/single-crystal diffractometer, and a four-circle diffractometer (FCD) for the determination of magnetic and crystal structures from small single crystals. At the Spallation Neutron Source (SNS), there are a high-resolution neutron time-of-flight (TOF) Laue diffractometer (TOPAZ) for small molecule and chemical crystallography, a macromolecular diffractometer (MaNDi), a diffuse scattering spectrometer focusing on quantum materials (CORELLI), and a high-pressure dual-purpose-powder and single crystal-diffractometer. The Oak Ridge National Laboratory (ORNL) neutron scattering facility hosts seven single-crystal diffractometers.
