Real‐time neutron powder diffraction and small‐angle scattering techniques have been developed on the TOF diffractometer DN‐2 at the IBR‐2 pulsed reactor at JINR (Dubna) with a total flux on the sample of 10 7 neutrons cm −2 s −1 and a resolution of about 1%. A special arrangement of the detector system ensures a high counting rate of diffracted neutrons. Depending upon sample type and experimental conditions, the measuring time t s of one neutron pattern varies from a few minutes to several seconds. The performance of the diffractometer is discussed and typical data are shown to demonstrate current achievements using real‐time techniques at a pulsed reactor.
