First tests on the gas-filled separator GRAND for the Super Heavy Element Factory at the Flerov Laboratory of Nuclear Reactions in JINR

Abstract

The gas-filled separator GRAND is experimental setup created for Super Heavy Element Factory of the FLNR (JINR). It is intended for experiments of the synthesis of super heavy elements and for study of their physical and chemical properties. The ion-optical parameters of the setup were checked using α-particle tracing from standard 226Ra and 244Cm sources. The complete fusion reaction of 208Pb(48Ca, xn)256No* was used for estimation of the transmission efficiency of recoil nuclei in the separator.
