Abstract

SPHERES is a third-generation neutron backscattering spectrometer, located at the 20 MW German neutron source FRM II and operated by the Jülich Centre for Neutron Science. It offers an energy resolution (fwhm) better than 0.65 μeV, a dynamic range of ± 31 μeV, and a signal-to-noise ratio of up to 1750:1.

摘要

SPHERES是一台第三代中子背散射光谱仪，位于功率为20兆瓦的德国中子源FRM II，并由于利希中子科学中心运营。它的能量分辨率（半高宽）优于0.65微电子伏特，动态范围为±31微电子伏特，信噪比高达1750:1。
