Possible upgrade of an existing tandem accelerator facility to an ISOL facility for neutron-rich rare isotope beams

The feasibility and utility of a Helium multi‐jet system to transport fission fragments vertically up to an ion source 50 m above ground level is explored. This idea opens up the possibility of using the existing 15‐UD tandem and SC linac accelerator system at Inter University Accelerator Center (IUAC) as a post accelerator for rare isotope beams (RIBs). This could considerably speed up the upgrade of the facility to a RIB facility since the driver accelerator (e.g. a 50 MeV electron accelerator) can be purchased. We find that such a facility will be competitive for refractory neutron‐rich isotopes and can later be combined with a positive ion injector to produce a large number of beam species with higher intensities.
