Abstract: Application of the Fourier technique for diffraction experiments at long pulse neutron sources is discussed. The main parameters of a neutron Fourier diffractometer are reviewed. A comparison of the parameters of the conventional TOF diffractometers at SPS and LPS with the possible characteristics of the Fourier diffractometer is carried out. The experience of operating of the HRFD instrument, the first neutron Fourier diffractometer at the LPS-type source, the IBR-2 pulsed reactor in Dubna, is discussed.

Keywords: neutron Fourier diffractometer, high resolution, powder diffraction, pulsed neutron source
