  During the recent years, at the FLNR a successful cycle of experiments has
been accomplished on the synthesis of the superheavy elements with Z=112 to
Z=118 using 48Ca ion beam. From the viewpoint of the detection of rare decays
and background suppression, this success was achieved due to the application of
a new radical technique, the method of active correlations. The method employs
search in a real time mode for a pointer to a probable correlation like recoil
alpha for switching the beam off. In the case of detection in the same detector
strip an additional alpha decay event, of beam OFF time interval is prolonged
automatically
