Abstract.

Gas stop** is the method of choice for converting rare isotope beams obtained via projectile fragmentation and in-flight separation into low-energy beams. Current gas stopper systems for high-energy beams are based on linear gas cells filled with 0.1–1 bar of helium. While successful for a number of experiments, they are limited in the maximum beam rates that can be used and exhibit long extraction times that can lead to decay losses for very short-lived isotopes. To avoid these limitations, a new type of gas stopper is being developed at the NSCL/MSU based on a cyclotron-type magnet with a stop** chamber filled with helium buffer gas at low pressure. RF-guiding techniques are used to extract the thermalized ions from the central region.
