/ Fraser, Matthew (CERN) ; Bernardes, Ana (CERN) ; Newborough, Antony (CERN) ; del Alamo, Daniel (CERN) ; Grenier-Boley, Edouard (CERN) ; Pozzi, Fabio (CERN) ; Di Giovanni, Gian Piero (CERN) ; Corso, Jean-Pierre (CERN) ; Vollaire, Joachim (CERN) ; Ferreira Somoza, Jose (CERN) et al.
Following the successful completion of the LHC Injectors Upgrade (LIU) project, since 2021 the Proton Synchrotron (PS) Booster has served the LHC injector chain with protons at an increased kinetic energy of 2 GeV. An upgrade of the ISOLDE (Isotope Separator On-Line DEvice) facility has long been considered to produce radioactive ion beams with a higher energy proton driver beam. [...]

Charge radii of thallium isotopes near the N=126 shell closure
/ IDS Collaboration
The changes in the mean-squared charge radius of Tlg209 (N=128) and Tlm207 (N=126) relative to Tl205 have been measured for the first time using the in-source laser resonance-ionization spectroscopy technique with the Laser Ion Source and Trap (LIST) at ISOLDE (CERN). The application of the LIST suppresses the dominant background from isobaric francium isotopes and allows access to thallium nuclides with A⩾207. [...]

First ion source at ISOL@MYRRHA with an improved thermal profile - Theoretical considerations
/ Hurier, S (SCK-CEN, Mol ; Leuven U.) ; Rijpstra, K (SCK-CEN, Mol) ; Ramos, J P (SCK-CEN, Mol) ; Popescu, L (SCK-CEN, Mol) ; Cocolios, T E (Leuven U.) ; Mancheva, R (Leuven U. ; CERN) ; Chrysalidis, K (CERN) ; Rothe, S (CERN) ; Au, M (CERN) ; Koliatos, A (CERN)
ISOL@MYRRHA will be a new Radioactive Ion Beam (RIB) facility in Belgium based on the Isotope Separation On-Line (ISOL) technique, and established within the framework of MYRRHA, the world’s first large-scale accelerator driven system project at power levels scalable to industrial systems. The surface ion source, or hot cavity, is chosen as initial source for its reliability and simple design. [...]

A two-step resonance photo-ionization scheme has been used to ionize samarium atoms in the SPES tantalum hot-cavity ion source. The effect of the ion load on the ion beam time structure and the laser enhancement of the ion yield has been studied at different ion source temperatures. [...]

Target Development towards First Production of High-Molar- Activity $^{44g}$Sc and $^{47}$Sc by Mass Separation at CERN-MEDICIS
/ Mamis, Edgars (CERN ; Latvia U.) ; Duchemin, Charlotte (CERN) ; Berlin, Valentina (CERN) ; Bernerd, Cyril (CERN) ; Bovigny, Mathieu (CERN) ; Chevallay, Eric (CERN) ; Crepieux, Bernard (CERN) ; Gadelshin, Vadim Maratovich (Mainz U., Inst. Phys.) ; Heinke, Reinhard (CERN) ; Hernandez, Ronaldo Mendez (CERN ; Havana, ISCTN) et al.
The radionuclides 43Sc, 44g/mSc, and 47Sc can be produced cost-effectively in sufficient yield for medical research and applications by irradiating natTi and natV target materials with protons. Maximizing the production yield of the therapeutic 47Sc in the highest cross section energy range of 24–70 MeV results in the co-production of long-lived, high-γ-ray-energy 46Sc and 48Sc contaminants if one does not use enriched target materials.

Scandium thermal release from activated natTi and natV target materials in mixed particle fields: Investigation of parameters relevant for isotope mass separation
/ Mamis, E (CERN ; Latvia U.) ; Kalnina, P (CERN ; Latvia U.) ; Duchemin, C (CERN) ; Lambert, L (CERN) ; Conan, N (CERN) ; Deschamps, M (CERN) ; Dorsival, A (CERN) ; Froeschl, R (CERN) ; Ruiz, F Ogallar (CERN) ; Theis, C (CERN) et al.
Scandium (Sc) has gained significant interest in nuclear medicine due to its 43Sc, 44g/mSc, and 47Sc radioactive isotopes being suitable for cancer diagnostics and therapy, offering a promising avenue for theranostics. Various production methods, including irradiation of enriched or naturally abundant calcium (Ca), titanium (Ti), and vanadium (V) materials with different particle beams, have been investigated to produce 43Sc, 44g/mSc, and 47Sc.
