Description
In order to address the demand for smaller samples and increased experimental availability from pulsed-source time-of-flight neutron spectroscopy instruments, we have developed the concept of symbiotic spectrometers for the European Spallation Source. Spectrometers in symbiosis share a single beam port and neutron guide, each utilizing independent parts of the extracted phase space.
Njord is a broad-bandwidth crystal-analyzer indirect-geometry spectrometer utilizing nested mirror optics for ambitious small-sample spectroscopy. Remora is a crystal-monochromator direct-geometry spectrometer leveraging principle- and higher-harmonic scattering repetition-rate-multiplication to produce useful experimental conditions from otherwise unused neutrons. Together they enable more and more-ambitious measurements in cold neutron spectroscopy, especially with very small samples, weak signals, or demanding sample environments.
Njord & Remora have been proposed for the ESS Instrument Roadmap, and their details plus how you can support the proposal will be presented.
