RADIOACTIVE ION-BEAMS AT THE BEVALAC - GREATLY ENHANCED FRAGMENT SEPARATION FOR HIGH-ENERGY BEAMS

[摘要] Radioactive beams are routinely produced at the Bevalac by the fragmentation process. High energy beams (energies approximately 800 MeV/u) produce fragments with nearly the original beam momentum, forming a radioactive ion beam. A new beamline is being constructed which will provide resolution for ions approaching the mass 100 region, compared to the present mass 20 capability, by strongly increasing the dispersion and also increasing the beam size for easier tuning and more effective collimation. In addition, the angular acceptance has been more than doubled. Details of the design will be presented.
