The Production and Acceleration of RIBs at ISAC‐I and Future Plans for ISAC‐II Available to Purchase

ISAC‐I at TRIUMF is now delivering intense beams of both low energy and accelerated radioactive ion beams (RIBs) for experiments. The post‐accelerator for ISAC‐I includes a room temperature RFQ and DTL operating cw to accelerate ions of A ⩽ 30 to a final energy fully variable from 0.153 to 1.53MeV/u. The design concept, machine status and early operating experience of the ISAC‐I linear accelerator complex will be summarized. TRIUMF has received funding through to 2005 to proceed with an extension to the ISAC facility, ISAC‐II, to permit acceleration of radio‐active ion beams above the Coulomb Barrier for masses up to 150. Central to the addition are a ECR charge state booster before the ISAC RFQ and a superconducting heavy ion linac. The accelerator design and present status of the project including superconducting rf developments will be presented.
