Description
Employing storage rings for precision physics experiments with highly-charged ions (HCI) is a powerful approach for probing fundamental questions at the intersection of atomic physics, nuclear structure, and astrophysics. Storage of freshly produced secondary particles in a storage ring is a straightforward way to achieve the most efficient use of these rare species.
Major facilities include the ESR and CRYRING at GSI, CSRe at IMPCAS, R3 at RIKEN, and the newly commissioning SRing at HIAF.
Precision mass measurements and investigations of exotic decays in highly charged ions are now well-established research programs. Still, the development of new techniques such as Br-defined isochronous mass spectrometry at the CSRe or combined Schottky+isochronous spectrometry at the ESR improves the experimental capabilities in terms of sensitivity, precision and measurement speed. For example, masses of short-lived nuclei produced with vanishingly small rates of below 1 particle per day can be obtained.
Beyond mass measurements, studies of nuclear reactions were intensified significantly in the recent years. Here, beam cooling combined with windowless thin gas targets enable high angular and energy resolution. Furthermore, beam accumulation and deceleration
enable reaction measurements with radioactive projectiles across a broad range of centre-of-mass energies — from a few ten keV/u of astrophysical interest to a few hundred MeV/u.
In this contribution, the most recent highlight results will be presented. The future perspectives at the existing and planned facilities will be outlined.
