A new analog spectrometer of the DGFRS2 setup installed at new FLNR DC-280 ultra-intense cyclotron has been designed. The main goal of application of this spectrometer is to provide deep backgrounds suppression in different heavy-ion induced nuclear reactions using real-time detection mode of short correlated sequences such as ER-α, α-α or even ER-α-α. Integral 1M CAMAC analog-to-digital processor ExTech ADP-16 is used as a basic unit in the spectrometer design. A new real-time flexible algorithm is presented in addition to the conventional ER-α one which is in use for a few years at the DGFRS1 setup installed at the U-400 FLNR cyclotron. Note that the spectrometer operates together with the 48×128 strip DSSD (Double Side Strip Detector) detector and low pressure pentane-filled gaseous detector. To perform the real-time operation mode, we define an abstract mathematical object like “correlation graph” containing n(n − 1)/2 links. An experimentalist can use each link as trigger signal for beam stop. Here n is the number of nodes for this graph. First tests of the spectrometer at intense beam of 48Ca projectile are presented too.
