摘要：
A longitudinal neutron resonance spin echo (L-NRSE) spectrometer combined with a MIEZE (modulated intensity with zero effort) configuration will be constructed at the C33 beam port at China Mianyang Research Reactor (CMRR). In the MIEZE mode, the analyzer is placed in front of the sample, and between the sample and the detector there is no other optical device. The MIEZE signal is sensitive to the neutron path length differences from the sample to the detector. In this work, we have analytically studied the effects of sample geometry, detector thickness, and experimental setup on the resolution function.
