ISOLDE target and ion source units are among the key components in the process chain towards the delivery of radioactive ion beams for nuclear physics experiments. Targets are manufactured on demand, following the physics schedule and beam request. Over the past 50 years more than 1000 isotopes have been produced from over 74 elements, but users constantly seek to study new, often more exotic...

The demand for new beams at the ISOLDE facility is constantly growing. For refractory elements such as the actinides, experiments face challenging or unknown yield and beam purity. More beam composition information in the actinide region is needed, and further target and ion source developments may be required. Forming volatile molecules has been explored as an avenue to improving the surface...

The electron gun of the REXEBIS charge breeder at the REX/HIE-ISOLDE post accelerator has been upgraded from a standard magneto-immersed type to a gun using a non-adiabatic magnetic element. The results from the commissioning of the new design are here presented, emphasizing aspects of interest for the users of the radioactive beams. In particular, the charge breeding efficiency have been...

During the 1980’s and 90’s, the Apparatus for Surface Physics and Interfaces at CERN (ASPIC) was instrumental to many Perturbed Angular Correlation (PAC) spectroscopy studies at ISOLDE [1]. The setup was dedicated to surface modification and characterization, coupled with precise control of the position of PAC probes, enabling investigations into the position of adatoms on film surfaces or the...

Frank Wienholtz for the PUMA collaboration
The main goal of the PUMA (antiProton Unstable Matter Annihilation) experiment is to use antiprotons as a tool to investigate properties of exotic nuclei. For this, antiprotons produced at the AD/CERN and decelerated by the ELENA storage ring will be captured, cooled and transported to the ISODLE facility where the antiprotons will be mixed with...

The contribution will give an update of the IBDRS study aiming at the upgrade of the ISOLDE GPS and HRS beam dumps. This challenging project will allow an increase of the proton beam power to ISOLDE. It will require the partial removal of earth shielding covering the target area. For the first time since 1991, when Booster-ISOLDE was built, it will be possible to access the faraday cages and...

A high yield radioactive ion beam (RIB) can be produced using the intense $\gamma$ beam of the Gamma Factory (GF) [1,2] facility proposed at CERN. The beam impinging on several thin actinide targets will generate exotic neutron-rich nuclei via the photo-fission reaction. The reaction takes place inside a high areal density with orthogonal extraction cryogenic stopping cell (HADO-CSC) [3] where...
