Abstract:
Abstract The neutron spin-echo (NSE) method, which is the most powerful tool of high-resolution neutron spectroscopy, is known in two versions: with the long solenoids and short alternating fields. Here we consider an alternative version that makes use of spin flippers consisting of thin magnetic foils (TMF) with an in-plane rotating magnetic field vector. MNCP simulations show the perfect performance of the NSE spectrometer build upon such flippers. The requirements for TMF are estimated. Some possible applications of such technique are discussed. This approach can be considered as an alternative to the present day NSE techniques.
