Abstract

A 42 MV Superconducting (SC) Booster Linac is proposed for the Holifield Radioactive Ion Beam Facility (HRIBF). The linac, consisting of 56 superconducting, quarter wave, 120 MHz, independently phased, 2 gap resonators, will be used to boost Radioactive Ion Beams (RIBs) accelerated by the 25 MV NEC tandem, to Coulomb barrier energies for use in nuclear physics research near the proton and neutron drip lines. The design potential of 42 MV is sufficient to boost the beams of mass 180 above the Coulomb barrier using the most probable charge state, 15+, from single foil stripping in the tandem terminal. Linac parameters and layout are presented with accompanying beam dynamic calculations. In addition, an upgrade of the existing pre-tandem beam bunching system is proposed to further preserve the RIB intensity through better longitudinal phase space matching into the linac
