Abstract

The Dubna Gas-Filled Recoil Separator (DGFRS) is the mostly effective setup in use for the field of synthesis of superheavy elements. Application of DSSSD detector provides more precise energy and position detection for both implanted recoils and their alpha decays. To minimize contribution of background products the method of fctive correlation is applied at the DGFRS. To apply this method a precise calibration for 48 front strips is strongly required. Method of three peaks auto calibration is proposed with a first approximation step with 9.26 MeV 217Th peaks. Examples of alpha-decay original spectra and spectra after filtration procedures are presented.
