SPHERES, Juelich's high-flux neutron backscattering spectrometer at FRM II

SPHERES is a third-generation neutron backscattering spectrometer, located at the 20 MW German neutron source FRM II and operated by the Juelich Centre for Neutron Science. It offers an energy resolution (fwhm) better than 0.65 mu eV, a dynamic range of plus or minus 31 mu eV, and a signal-to-noise...
