Description
An upgraded version of the DGFRS-2 (the Dubna Gas-Filled Recoil Separator-2) analog spectrometer to search for rare ER-α correlated sequence in a real-time mode to suppress radically cyclotron associated background signals is presented. New “flexible” algorithm to operate with new analog spectrometer of the DGFRS-2 installed at DC-280 (the JINR Superheavy Element Factory) cyclotron setup is under consideration. The main goal of application of this algorithm is to search an optimal time correlation recoil-alpha parameter directly during the acquisition C++ YDS code execution [1-4]. Note that the spectrometer operates together with the 48×128 strip DSSD (Double Side Strip Detector) detector and low pressure pentane-filled gaseous detector (~1.2 Tor; 80 x 230 mm2) are presented schematically. First beam test results in 48Ca and 242Pu, 243Am, 232Th and 238U targets induced nuclear reactions are presented too [5-7]. Registered implanted ER spectra are compared with calculated ones. Some attention is paid to stability tests. Half life systematic for Z=119,120 are considered in brief in connection with active correlation method application.
