Polarised neutron scattering instrument with time-of-flight inelastic scattering option
This instrument is focussed on cold neutrons. All parameters given here are valid during the current operation of FRM II. Please get in touch with the instrument team well in advance for all further details (length of experiment etc.).
DNS is a versatile polarised neutron scattering instrument that is ideally suited to study both short-range and long-range magnetic correlations in quantum materials, strongly correlated electrons, unconventional superconductors, and functional magnetic materials. In addition to the diffraction mode, DNS also provides an option with time-of-flight inelastic neutron scattering, which can be used for the measurements of low-energy magnetic excitations.
With its compact size, a new-generation Fe/Si based focusing polarising bender and wide-angle polarisation analysers, DNS is optimised as a high intensity polarised instrument with medium resolution. It allows for the unambiguous separation of nuclear coherent, spin incoherent, and magnetic scattering contributions simultaneously over a large range of scattering vector Q and energy transfer E.
DNS can be operated in both elastic and inelastic scattering mode with a wide range of applications,Polarised elastic scattering options:
