New experimental setup for high-precision mass measurement of heavy and superheavy nuclei is being built at the Flerov Laboratory of Nuclear Reactions in Dubna. It consists of a target unit, a gas-filled separator of complete fusion products, a cryogenic gas stopping cell (CGSC), a radiofrequency system for transporting and cooling a low-energy beam, and a multireflection time-of-flight mass spectrometer. Simulations of stopping efficiency and time of extraction from CGSC were performed for evaporation residues of the complete fusion reactions *4*0Ar + *1*4*4Sm *> &sup(184−x)Hg + xn, *4*0Ar + *1*6*6 Er *> &sup(206−x)Rn + xn, *4*8Ca + *2*0*8Pb *> &sup(256−x)No + xn, and *4*8Ca + *2*4*2 Pu *> &sup(290−x)Fl + xn. Internal software based on SRIM and Geant4 was used in the simulations. Optimum parameters for the real experiment, namely, the width of entrance window, pressure of helium buffer-gas in CGSC, and the choice of suitable reactions were the main motivation of these simulations.
