Abstract

This article describes a high-charge-state linear post accelerator for enhancing the number and intensities of short-lived radioactive nuclei at the Holifield Radioactive Ion Beam facility (HRIBF). The system consists of a room temperature RFQ, a normal conducting IH linac and a SC QWR linac that is designed to either bypass or post accelerate beams from the 25-MV tandem. The voltage gain of the linac system will reach 60 MV making possible the acceleration of ions with masses, M⩽150, above the Coulomb barrier. Since the linac accelerates positive-ion beams, it will increase the number of elements that can be delivered for research by a factor of ~3 and the intensity of a given species by orders of magnitude over those of the present HRIBF
