IN15 - Spin-echo spectrometer with time-of-flight option
IN15 is a high energy and momentum resolution spin-echo spectrometer optimised for quasielastic small angle scattering. This instrument has been jointly constructed by ILL, FZ Juelich, HMI Berlin, upgraded in 2014 by ILL and TU Berlin via BMBF grants 05K10KT1, 05K13KT1 and FZ Jülich.
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 spins as a timer. This spectrometry has unmatched sensitivity and is mainly used to investigate very slow collective movements.
Typical applications include:
