Astron.) ; Centofante, L (INFN, Legnaro) ; Chrysalidis, K (CERN) ; Crepieux, B (CERN) ; Fedosseev, V N (CERN) ; Heinke, R (CERN) ; Marchi, T (INFN, Legnaro) et al.
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.

U.) ; Sawitzki, Zoe (Leuven U.) ; Talip, Zeynep (PSI, Villigen) et al.
Background
In order to support the ongoing research across Europe to facilitate access to novel radionuclides, the PRISMAP consortium (European medical radionuclides programme) was established to offer the broadest catalog of non-conventional radionuclides for medical and translational research. The aim of this article is to introduce readers with current status of novel radionuclides in Europe.
Main body
A consortium questionnaire was disseminated through the PRISMAP consortium and user community, professional associations and preclinical/clinical end users in Europe and the current status of clinical end-users in nuclear medicine were identified. [...]
