SIRIUS: A Proposal for an accelerated Radioactive Beams Facility at ISIS

A Proposal for a future Radioactive Beams Facility has been developed based on ISIS, the world’s brightest pulsed neutron source. Radioactive ions are produced by the spallation process driven by a 100 μA, 800 MeV proton beam delivered from the ISIS synchrotron accelerator. This is ten times more powerful than currently available in the world today, and follows on from the successful work performed by the RIST project [1] to develop a high power radioactive beam target for such a facility. The proposed design provides for both low (200 keV), and high energy (10 MeV/A) radioactive beams with high to medium mass resolution. A flexible facility layout allows the maximum simultaneous and independent use of the radioactive beams by a number of different users. An overview of the proposed facility is presented.
