Abstract :
A new gas-cooled rotating target system was developed for the heaviest element production. A target wheel with a diameter of 30.0 cm could be rotated up to 3000 rpm. A helium gas introduced into the target chamber mounted upstream of a gas-filled recoil separator, which enables an effective gas cooling of the target. The development has led to the successful production of heavy nuclides via cold fusion reactions of 208Pb(64Ni,n)271Ds, 209Bi(64Ni,n)272Rg, 208Pb(70Zn,n)277112, and 209Bi(70Zn,n)278113.
