Stopped and Re-accelerated Exotic Beams at the NSCL

NSCL is developing a prototypical facility to demonstrate the technical feasibility and performance characteristics for stopping and re-accelerating beams of rare isotopes produced and separated in flight, as an important step towards a next-generation rare-isotope facility in the United States. Beams of rare isotopes will be produced and separated in-flight at the NSCL Coupled Cyclotron Facility and subsequently stopped and re-accelerated efficiently and with minimum losses. This involves three steps:

• Stopping of exotic beams in a novel cyclotron gas stopper.
• Breeding the stopped ions to high charges in a state-of-the-art EBIT-type breeder.
• Re-accelerating the ions in a modern superconducting linear accelerator.

NSCL will be the first facility worldwide to demonstrate and optimize the complete concept of creating fast exotic beams, stopping, breeding, and re-accelerating them. We apply innovative concepts to make the process cheaper and more efficient.
