Abstract

Over recent decades, the diffraction of thermal neutrons has become a powerful tool for solving various actual problems of materials science. To carry out scientific investigations on this theme, a neutron time-of-flight Fourier diffractometer FSD was developed and has been successfully operated for many years at the IBR-2 pulsed reactor in the Frank Laboratory of Neutron Physics, Joint Institute for Nuclear Research, Dubna. To ensure high resolution of the instrument, a special correlation technique is used, i.e., a fast Fourier chopper for modulation of the primary-neutron-beam intensity and the reverse time-of-flight method for data acquisition. The current state of the FSD diffractometer and its capabilities are described and examples of performed experiments are given.
