Spin-echo spectrometer with time-of-flight option and focussing option

IN15 is a high energy and momentum resolution spin-echo spectrometer optimised for quasielastic small angle scattering. This instrument is developed and financed jointly by the ILL, FZ Jülich and HMI Berlin.

Applications

The neutron spin echo technique is a unique inelastic scattering technique that measures velocity changes experienced by neutrons when they interact with matter by using their spin ½ as a timer. This spectrometry has unmatched sensitivity and it mainly makes possible the analysis of very slow atomic or molecular diffusive movements. Typically, the relaxation times and the distances that can be accessed with IN15 are 0.001 to 250 ns and 1 to 500 Å respectively.
