Design of a compact superconducting recoil separator for HIE-ISOLDE / Resta-López, J (Valencia U.) ; Foussat, A (CERN) ; Kirby, G (CERN) ; Rodin, V (CERN) ; Kirby, O (PSI, Villigen) ; Martel, I (Huelva U.) ; Welsch, C P (Cockcroft Inst. Accel. Sci. Tech. ; Liverpool U.)
The High Intensity and Energy ISOLDE facility (HIE-ISOLDE) at CERN has unprecedentedly expanded the research capabilities to investigate the structure of the atomic nucleus and the nuclear interaction. In this context, to meet the high-resolution mass spectroscopy required by the HIE-ISOLDE physics program, an innovative spectrometer is currently being designed, the ISOLDE Superconducting Recoil Separator (ISRS).

Commissioning of the RFQcb at the Isolde Offline 2 target test facility / Schuett, M (CERN) ; Rothe, S (CERN) ; Au, M (CERN ; Mainz U.) ; Koliatos, A (CERN) ; Bissell, M (CERN) ; Bidault, N (CERN) ; Le, L (CERN) ; Boucherie, A (CERN) ; Heinke, R (CERN) ; Chrysalidis, K (CERN) et al.
The Offline 2 mass separator laboratory is part of the CERN-ISOLDE Offline facilities - a suite of installations required to perform essential quality control on target and ion source units before irradiation at CERN-ISOLDE. The facility is also used for offline studies as a prerequisite before conducting any beam development on-line, especially establishing systematic effects. [...]

Nuclear physics in the N≈126 region relevant for the $r$ process / Podolyák, Zsolt (CERN ; Surrey U.)
Understanding how the heavy chemical elements are made in the astrophysical $r$-process requires information on both the properties of the nuclei involved and that of the environment. The availability of experimental information on the neutron-rich N∼126 nuclei is discussed, with emphasis on phenomena specifically relevant to this region: the large role of first-forbidden $\beta$ decays, and that of the $\Delta n = 0$ selection rule in Gamow-Teller decays. [...]

Beta decay along the N=Z line and its relevance in rp-process and X-Ray bursts / IS570 Collaboration
Nucleosynthesis in Type I X-ray bursts (XRB) proceeds eventually through the rp-process near the proton drip-line. Several N=Z nuclei act as waiting points in the reaction network chain. [...]

A setup for vacuum-ultraviolet spectroscopy of the $^{229}$Th low-energy isomer / Kraemer, Sandro (KU Leuven ; LMU, Garching) ; Chhetri, Premaditya (KU Leuven) ; Bara, Silvia (KU Leuven) ; Claessens, Arno (KU Leuven) ; De Witte, Hilde (KU Leuven) ; Elskens, Yens (KU Leuven) ; Ferrer, Rafael (KU Leuven) ; Kudryavtsev, Yuri (KU Leuven) ; Sels, Simon (KU Leuven) ; Van Den Bergh, Paul (KU Leuven) et al.
The ground-state transition of the low-energy isomer in $^{229}$Th has been proposed as the basis for the development of a novel optical clock as a tool for fundamental-physics studies. Vacuum-ultraviolet studies of the 𝛽-decay of 229Ac recently enabled to measure the de-excitation energy of the isomer with a sevenfold improvement in precision compared to previous results by directly observing photons from the isomer’s radiative decay.

Proton halo effects in the $^{8}$B+$^{64}$Zn collision around the Coulomb barrier / Di Pietro, A (INFN, LNS) ; Spartá, R (INFN, LNS ; DAPNIA, Saclay) ; Figuera, P (INFN, LNS) ; Tengblad, O (Madrid, Inst. Estructura Materia) ; Moro, A (Seville U.) ; Lei, J (Pisa U.) ; Garcia, JP Fernandez (Seville U.) ; Acosta, L (INFN, LNS ; Chalmers U. Tech.) ; Jonson, B (Chalmers U. Tech.) ; Borge, MJ (Madrid, Inst. Estructura Materia) et al.
The $^{8}$B+$^{64}$Zn reaction at 38.5 MeV has been studied at HIE-ISOLDE CERN to investigate proton halo effect on the reaction dynamics. For the first time it was used the only existing post-accelerated $^{8}$B beam. [...]

Developments at the CERN-ISOLDE Offline 2 mass separator / Schuett, Maximilian (CERN) ; Au, Mia (CERN ; Mainz U.) ; Bissell, Mark (CERN) ; Bidault, Niels (CERN) ; Koliatos, Alexandros (CERN) ; Le, Line (CERN) ; Azaryan, Nikolay (CERN) ; Heinke, Reinhard (CERN) ; Chrysalidis, Katerina (CERN) ; Rothe, Sebastian (CERN)
The Offline 2 mass separator laboratory is part of the CERN-ISOLDE Offline facilities - a suite of installations required to perform essential quality control on target and ion source units before irradiation at CERN-ISOLDE (Catherall et al., 2017) [1]. The facility is also used for extended preparatory offline studies as a prerequisite before conducting any beam development on-line, especially establishing systematic effects. [...]

Targets and ion sources at CERN-ISOLDE — Facilities and developments / Rothe, S (CERN) ; Au, M (CERN ; Mainz U.) ; Ballof, J (CERN ; Mainz U.) ; Barbero, E (CERN) ; Bissell, M (CERN) ; Boucherie, A (CERN) ; Bovigny, M (CERN) ; Chrysalidis, K (CERN) ; Crepieux, B (CERN) ; Cruikshank, J (CERN) et al.
At the CERN-ISOLDE radioactive ion beam facility, thick targets are irradiated using a beam of 1.4-GeV protons. One of ISOLDE’s key features is the large choice of ion source types and target materials available, enabling us to select the ideal combination for optimal intensity and purity of the isotopes requested by ISOLDE users.

Reconditioning of the Leuven Isotope Separator as a test bench for radioactive ion beam development / Wojtaczka, Wiktoria (Leuven U.) ; Caerts, Bart (Leuven U.) ; Heines, Michael (Leuven U.) ; Johnson, Jake D (Leuven U.) ; Rothe, Sebastian (CERN) ; Cocolios, Thomas E (Leuven U.)
Producing novel medical radionuclides in the quantities necessary for pre-clinical and clinical use requires an ion source able to handle high ion throughputs, operated efficiently, to deliver high specific activity samples. This is only possible with the understanding of how different parameters affect the ion source performance. [...]
