"Diffractometers at the NEPTUN pulsed reactor"
S. V. Sumnikov

The design and characteristics of diffractometers of the first-stage for the new neutron source NEPTUN at FLNP JINR are discussed. The concept of diffractometers takes into account the existing experience of their operation at the IBR-2 reactor and worldwide trends. The proposed diffractometers in a number of key parameters will be significantly superior to the instruments operating at IBR-2. Their creation will make it possible to successfully solve almost any modern problems of structural neutronography.
