abstract = {Neutron spin echo (NSE) spectroscopy provides the ultimate
energy resolution in quasi-elas- tic thermal and cold
neutron scattering spectroscopy. In 2017 the Jülich neutron
spin echoat MLZ went through a refurbishment of the
secondary spectrometer: The old normal con- ducting
main-precession coils have been replaced by a new set of
fringe-field compensated, superconducting magnets that were
realized following the results obtained for the designof
ESSENSE, the proposed high-resolution NSE spectrometer at
the ESS. One of the most innovative characteristics of the
coils is their optimized geometry that maximizes the
intrinsic field-integral homogeneity along the flight-path
of the neutrons and that enhances the reso- lution of a
factor 2.5, as the first experiments could already confirm.
The new configuration yields an improved resolution that may
be exploited to reach larger Fourier-times and/or to benefit
from significant intensity gains if shorter neutron
wavelengths are used at a given Fou- rier-time. Thus the new
J-NSE Phoenix meets the needs to look into the microscopic
dynam- ics of soft- or –biological matter with enhanced
and new quality. Here we present the results on the
performance of the spectrometer after the refurbishment and
some selected examples from the realm of soft matter
dynamics that largely rely on the enhanced properties of the
new J-NSE.},
