Neutron Resonance Spin Echo Method and Its Application

Abstract

New types of neutron spin echo using Resonance Spin Flippers (RSFs) have been developed which are called Modulated IntEnsity by Zero Effort (MIEZE) and Neutron Resonance Spin Echo (NRSE). In NRSE, two RSFs replace a homogeneous static magnetic field for spin precession in the Mezei-type NSE spectrometer. In the MIEZE spectrometer, the sample is placed after the analyzer and there are no optical components between the sample and the detector. The principles of the NRSE and MIEZE techniques are introduced.
