  In this paper, we present the results of the first beam tests of the
detection system at the focal plane of the Dubna Gas-Filled Recoil Separator-2
(DGFRS-2), which receives beams from the DC-280 FLNR cyclotron. The high beam
intensity of $^{48}$Ca$^{+10}$ heavy ions from the cyclotron enables us to
obtain a number of superheavy recoils sufficient to compare both the measured
and calculated spectra of superheavy recoils implanted into a silicon detector.
A real-time algorithm to search for an Evaporation Residue (ER) -- $\alpha$
correlated sequences is described in brief. It should be noted that the DGFRS-2
spectrometer operates in conjunction with the 48x128 strip DSSD (Double-sided
Silicon Strip Detector; 48x226 mm2) detector and a low-pressure pentane-filled
gaseous detector (1.2 Torr; 80x230 mm$^2$). A block-diagram of the spectrometer
and the event format are also presented. Special attention is paid to the
response of a low-pressure pentane-filled DeltaE multiwire proportional chamber
for recoils of Fl, synthesized in the $^{242}$Pu+$^{48}$Ca $\to$ $^{287}$Fl +3n
complete fusion nuclear reaction. Some actual parameters of the detection
system have also been extracted from $^{\rm nat}$Yb + $^{48}$Ca, $^{232}$Th +
$^{48}$Ca, $^{243}$Am + $^{48}$Ca, $^{238}$U + $^{48}$Ca reactions. The effect
of neighbor strip charge sharing for the ohmic side of the DSSD detector is
also under consideration.
