Larmor labeling is seen as one of the key ingredients in the development of novel neutron instrumentation. FLEXX puts special emphasis on exploiting the neutron resonance spin echo (NRSE) technique for high-resolution spectroscopy on dispersive quasi-particle excitations. This enables unique measurements in single crystal spectroscopy over large portions of the Brillouin zone. To keep the experimental opportunities at BER II at the forefront the NRSE option available at FLEXX was upgraded along with the change of the primary spectrometer . In user service upgraded V2/FLEXX provides new capabilities for quantum magnetism, heavy-fermion systems and unconventional superconductivity. For example inelastic experiments in magnetic fields up to 17 T are now proven to be feasible. Energy research with inelastic neutron instruments will be strengthened through inhouse research, thereby fostering collaborations with external partners. The research themes at the new FLEXX spectrometer in future will be centered on transport properties in thermoelectric materials.
