Neutron phase-echo concept and a proposal for a dynamical neutron polarisation method

Chapter II. Neutron Spin Echo Experiments
Part of the Lecture Notes in Physics book series (LNP, volume 128)


Experiments in the field of neutron interferometry can be interpreted in terms of a neutron phase-echo concept, which is closely related to the spin-echo concept. Phase echo analysis can be done even with unpolarized neutron beams if coherence between separate beams exists. Furthermore a method is proposed for a dynamical polarization of a neutron beam due to the combination of a momentum separation and a spin overlapping part. This system consists of a multistage h.f. flipper and one half of a spin-echo spectrometer and allows an optimal use of available neutrons.
