SPHERES, Julich'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 Julich Centre for Neutron Science. It offers an energy resolution (fwhm) better than 0.65 mu eV, a dynamic range of +/- 31 mu eV, and a signal-to-noise ratio of up to 1750:1. (C) 2012 American Institute of Physics.
