The high quality and selectivity of the ISOLDE beams allows high-precision measurements of nuclear structure phenomena. In the period of 2001-2012 ISOLDE offered the largest variety of post-accelerated radioactive beams in the world up to an energy of 3 MeV/u. In order to broaden the scientific opportunities, the HIE-ISOLDE (High Intensity & Energy) project will increase the final energy of...

The TSR will be the first low-energy storage ring at an ISOL-type radioactive
beam facility [1]. Specifically, we intend to setup the heavy-ion, low-energy ring TSR at the ISOLDE facility in CERN, Geneva. Such a facility will provide a capability for experiments with stored secondary beams that is unique in the world. The envisaged physics programme is rich and varied, spanning from...

The REXEBIS charge breeder provides the HIE-ISOLDE linac with highly charged ions such as 2< A/q<4.5. Only for lighter ions the low A/q-values can be obtained (fully stripped ions to reachable Z=20), partly because of the limited electron beam energy, but also due to the limited electron current density.
As the electron cooling time is inversely proportional to the square of the ion charge,...

The introduction of cryogenically cooled, few micrometer-sized nozzle geometries and an essential modification of the experimental storage ring (ESR) target station for the first time allowed for a reliable operation using the light target gases helium and hydrogen at area densities up to values of 10$^{14}$ cm$^{-2}$ [1]. In the course of these optimization efforts, a remarkably versatile...

Recently transfer-induced fission experiments where proposed at TSR@ISOLDE, requiring luminosities in the 1027 1/(s cm2) range. In the talk the feasibility of those experiments from the accelerator point and as well the achievable luminosity will be discussed.
Furthermore experiments with the external spectrometer HELIOS needs ion beams with transverse emittances of about 0.01 mm mrad ...

Laser spectroscopy is an atomic technique, which gives access to nuclear observables independently of nuclear models. The hyperfine structure reveals the nuclear spin and nuclear electromagnetic moments, while the isotope shift between any two isotopes is related to the change in the nuclear mean square charge radius.
There are limitations to laser spectroscopy related to the atomic system...

Injecting beams of radioactive nuclei into the TSR and cooling them will make it possible to perform charged-particle spectroscopy experiments with excellent energy resolution. For low-Z beam species, nuclear reactions in a gas-jet target can be studied in the ring, with the beam passing through the target repeatedly to achieve high luminosities. However, for heavier beam species higher...

Beta-decay is a well-established technique to investigate the structure of nuclei. In light exotic nuclei the decay is characterised by large Q-values and low breakup thresholds in the daughter nuclei, so that feeding to continuum states and delayed emission of nucleons and light ions become possible. These processes have been used to study the peculiar features of those systems, such as halos...

With online radioactive beams or with a standalone ion source, and with a suitable injector, the TSR storage ring can be used to study multiply charged ions of many elements and in many charge states. This makes the storage ring a unique tool for studies at the borderline of atomic and nuclear physics, also serving astrophysics and fusion energy research. Recent achievements in this research...

In this presentation I will try to give an overview of the present and planned storage ring projects worldwide. I will concentrate on the planned research program and will discuss the unique as well as overlapping physics cases.
