The main goal of creation of a Superheavy Element Factory at the Flerov Laboratory of Nuclear Reactions (FLNR) is to sufficiently improve the efficiency of studies on heavy and superheavy nuclei. The factory will be based on a high-current DC-280 cyclotron. The use of beams with the intensity up to 6 x 10(13) s(-1) (10 p mu A) requires effective separators providing high suppression of unwanted reaction products. Following the analysis of the kinematic characteristics of several hundreds of reactions, a conclusion was drawn that it is necessary to construct three separators optimized for specific tasks: a universal gas-filled separator for synthesis and study of the properties of heavy isotopes, a velocity filter for spectroscopic investigations, and a pre-separator for further chemical separation and precise mass measurements.
