Method of active correlations: Present status

Abstract

During the recent years, at the FLNR (JINR) a successful cycle of experiments has been accomplished on the synthesis of the superheavy elements with Z=112–118 with 48Ca 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. Reasonable scenarios of developing the method are considered. PC based data acquisition system as well as the monitoring and control system of the Dubna Gas Filled Recoil Separator is considered in brief too.
