N2 - The instrumental layout and technical realisation of the neutron resonant spin echo (NRSE)spectrometer RESEDA at the Heinz Maier-Leibnitz Zentrum (MLZ)in Garching, Germany, is presented. RESEDA is based on a longitudinal field configuration, boosting both dynamic range and maximum resolution of the spectrometer compared to the conventional transverse layout. The resonant neutron spin echo technique enables the realisation of two complementary implementations: A longitudinal NRSE (LNRSE)option comparable to the classical neutron spin echo (NSE)method for highest energy resolution and large momentum transfers as well as a Modulation of Intensity with Zero Effort (MIEZE)option for depolarising samples or sample environments such as high magnetic fields, and strong incoherent scattering samples. With their outstanding dynamic range, exceeding nominally seven orders of magnitude, both options cover new fields for ultra-high resolution neutron spectroscopy in hard and soft condensed matter systems. In this paper the concept of RESEDA as well as the technical realisation along with reference measurements are reported.
