A new neutron spin echo (NSE) spectrometer using multilayer spin splitter (
MSS) is proposed. Two MSSs are arranged in (+ +) configuration for the quan
tum precession of neutrons. The NSE spectrometer requires only a small magn
et and is compact. Detailed discussion on the requirements for MSS is prese
nted using the results of Zygo interferometer. (C) 1999 Elsevier Science B.
