A new algorithm for the analog spectrometer of the DGFRS-2 setup installed at DC-280 cyclotron is presented. The main goal of application of this algorithm is to search an optimal time correlation recoilalpha parameter directly during the acquisition C++ code execution. A new real-time flexible algorithm in addition to the conventional ER − α algorithm, which has been used for a several years at the DGFRS-1 setup installed at the U-400 FLNR cyclotron, is presented. The main parts of the spectrometer are a 48×128 strip DSSD detector (Double Side Strip Detector) and a low-pressure gaseous detector. They are presented schematically. Nuclear reactions for synthesis of element Z=119 at the DGFRS-2 are under consideration. Some attention is paid to computer simulation of the heavy recoil spectra, taking into account its pulse height defect in silicon. First beam test results are also presented. A new formula for half-life time using recent data for superheavy nuclei is obtained
