AB  - With its compact design, large double-focus monochromator and wide-angle polarization analysis, DNS is optimized as a high intensity medium resolution cold-neutron polarized instrument at MLZ. Major instrument upgrades, including the installations of a new Fe/Si supermirror based focusing polarizing bender [1], a 300 Hz disc chopper system, and a neutron velocity selector for high-order rejection, have been accomplished recently. In addition to the resulted significant performance gain, this has also allowed to combine polarized neutrons with time-of-flight spectroscopy for the studies of emergent quantum materials, such as quantum spin liquid, quantum spin ice, Kitaev materials and correlated topological materials etc. In this presentation, an overview about the recent major instrument upgrades and some selected examples [2-5] on the studies of quantum materials will be given.[1] K.
