Abstract:We propose a high resolution neutron spectrometer, which combines the spin-echo principle with the separated coil magnetic resonance technique. The introduction of magnetic resonance instead of static spin-flippers in the spin-echo spectrometer allows the replacement of its high magnetic fields by low guide fields. The new technique represents a generalisation of the conventional spin-echo spectrometer.This property also holds for the double statistical-[8] the double Fourier- [9] and the Fotof-spectrometer [10], but those have not been built to our knowledge
