Low-energy nuclear reactions with stored ions: a new era of astrophysical experiments at heavy ion storage rings

Abstract

Heavy ion storage rings are powerful tools to store and observe key nuclear properties of rare radioactive isotopes. Recent developments in ring physics and enhanced beam intensities have now opened up the possibility to carry out low-energy investigations of nuclear reactions at rings. Pure, intense, exotic beams of isotopes that are otherwise challenging to access can be impinged on pure, ultra-thin targets, allowing the study of long-standing nuclear astrophysical puzzles in a variety of stellar sites that have so far resisted traditional approaches. In this review paper, we will describe pioneering studies with decelerated beams at the ESR storage ring at GSI (Germany), as well as future exciting prospects at the ESR and CRYRING at GSI/FAIR.

Precision nuclear physics experiments and theory

“…The papers dedicated to astrophysics include a contribution on low-energy nuclear reactions with stored ions; entitled A New Era of Astrophysical Experiments at Heavy Ion Storage Rings, by Glorius and Bruno [1]. This paper describes the recent developments in ring physics.…”

Storage, accumulation and deceleration of secondary beams for nuclear astrophysics

“…Glorius) became available in the last decade. The emergence of ultra-high vacuum detection systems, efficient postdeceleration of secondary beams and powerful storedbeam diagnostics eventually triggered a new era of experimental endeavors addressing direct reaction studies at low-energies [3][4][5].…”
