Abstract
We describe a new time-of-flight Fourier spectrometer for investigation of UCN diffraction by a moving grating. The device operates in the regime of a discrete set of modulation frequencies. The results of the first experiments show that the spectrometer may be used for obtaining UCN energy spectra in the energy range of 60200 neV with a resolution of about 5 neV. The accuracy of determination of the line position was estimated to be several units of eV
