| Presently, the ISAC facility produces radioactive ions by a single driver beam of up to 100microA of 500MeV protons (50kW) impinging on either of two production targets which are configured such that only one radioactive ion beam (RIB) is available for use at any one time; and the experimental hours are shared between several facilities in the low energy and two accelerated beam experimental areas. The ISAC-III upgrade is proposed to increase the number of RIBs simultaneously available to three. The upgrade involves the addition of a high power electron linac, 50MeV/10mA, that would irradiate one of two new independent targets and produce RIBs through photo-fission. A second beamline from the existing cyclotron would deliver an additional 500MeV 200microA proton beam to the new target area to irradiate the second target producing the third simultaneous beam. The proposal includes an additional post-accelerator front-end to augment the existing infrastructure to provide the capability of accelerating two of the RIBs simultaneously. The paper summarizes the upgrade and discusses design choices to optimize nuclide availability across the three experimental areas. |
