Since the early 1960s it is known that spin resonance in undulatory static magnetic fields allows for wavelength - selective spin flip of polarised neutrons. Implementing a novel travelling -wave technique, we have developed this concept towards a resonator which does not only allow to monochromatise the neutron beam but also to chop it into a sequence of pulses short enough for time - of - flight applications. The outstanding performance of such a resonator which was optimised for very cold neutrons could be demonstrated successfully at the PF2 - VCN beam line.
