Development of Gas-jet Transport System Coupled to the RIKEN Gas-filled Recoil Ion Separator GARIS for Superheavy Element Chemistry
A gas-jet transport system for the superheavy element chemistry was coupled to the gas-filled recoil ion separator GARIS at the RIKEN Linear Accelerator. The performance of the system was investigated using 206 Fr and 245 Fm produced in the 40 Ar-induced reactions on 169 Tm and 208 Pb targets, respectively. Alpha particles of 206 Fr and 245 Fm separated with GARIS and transported by the gas-jet were measured with a rotating wheel system for α spectrometry under low background condition. The high gas-jet efficiency of over 80% was found to be independent of the beam intensity up to 2 particle µA. These results suggest that the GARIS/gas-jet system is a promising tool for future superheavy element chemistry at RIKEN.
