The scientific case for advanced, high intensity radioactive beam facilities has been made repeatedly by the world-wide nuclear science community. As a result several such facilities of various scopes and based on a wide variety of technologies were proposed and are in various stages of planning and construction. This presentation will compare the capabilities of these next-generation projects and review their technological challenges. These facilities will be based on several types of isotope production accelerators with beam powers from a few kilowatts to megawatts, and will utilize driver beams from protons to uranium. Also, they are generally divided between ISOL-type (light ion drivers) and beam-fragmentation facilities (heavy ion drivers). Secondary, radioactive beams can be available at ion source energy or stopped, as in-flight beams following fragment separators and delivered for research at high energies, or as beams reaccelerated from ISOL-type ion sources or after stopping in gas catchers. The different facility types face a variety of technological challenges that must be overcome to reach their full potential.
