【 摘 要 】

The new neutron vibrational spectrometer LAGRANGE replaces the Be filter spectrometer placed on the hot source at the Institut Laue-Langevin. Lagrange provides much higher sensitivity to extremely small or low scattering samples through substantially increased detector count rate combined with considerably improved energy resolution. It opens new possibilities for the spectroscopic studies of complex materials. The new instrument permits investigation of much smaller samples, inherent in novel materials studies, recording of well- resolved vibration spectra. Lagrange is fully operational for users since 2012.
