Observation of MIEZE signal with an effective frequency of 1MHz

We developed a modulated intensity of zero effort (MIEZE) spectrometer with an effective frequency of 1MHz. Three resonance spin flippers (RSFs) and two-dimentional position sensitive detector (2D-PSD) were used for the MIEZE spectrometer. The frequency of RSFs was 0.5MHz and 2D-PSD works in TOF mod...

Zusammenfassung:We developed a modulated intensity of zero effort (MIEZE) spectrometer with an effective frequency of 1MHz. Three resonance spin flippers (RSFs) and two-dimentional position sensitive detector (2D-PSD) were used for the MIEZE spectrometer. The frequency of RSFs was 0.5MHz and 2D-PSD works in TOF mode with 100ns. The incident neutron wavelength was 0.81nm and the distance between sample position and detector position was 0.5m. The Fourier time was estimated to be 1.7ns. The contrast of the 1MHz echo signal was 0.4.
