Abstract
The physics opportunities made possible by beams of rare isotopes are
among the richest available in nuclear science. The rare-isotope
accelerator (RIA) now under development is an innovative accelerator that
will define the state of the art for all such facilities. A novel aspect of
the RIA project is the conversion of the most intense high-energy heavy-ion
beams into both fast and reaccelerated exotic beams. Along with target
fragmentation in next-generation high-power ISOL targets, RIA will use
projectile fragmentation in a high-energy separator/gas-filled ion collector
system to provide an extensive range of thermalized ions for reacceleration.
In addition, a second high-energy separator will provide the same or larger
range of ions for high-energy experiments. A brief overview of the RIA
accelerator concept, the layout of the facility, and production techniques
will be given along with information on the present R&D efforts in gaseous-ion collection.
