Time-of-flight isotope separator for a second-generation ISOL facility

Abstract

We focus on the study of a low energy and a high resolving power separator dedicated for an exotic isotope accelerator facility. The approach is based on the use of a time-of-flight technique in a long isochronous section. Different ion species are bunched and then separated in time, in an energy-isochronous section. We then transform the time shift in a transverse shift by a chopper in order to eliminate the unwanted ions using slits. A mass-resolving power of R M=10,000 seems feasible for low energy, multi-charged or mono-charged beams with a transverse acceptance up to 50 πmm mrad.
