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.

We report on the development, characterization, and first application of a specialized resonance ionization laser ion source for high-resolution spectroscopy applications below usual hot cavity Doppler broadening limitations, for on-line experiments at CERN-ISOLDE. The new PI-LIST ion source comprises perpendicular laser/atom beam interaction in a radio-frequency quadrupole unit directly downstream the hot atomizer cavity. [...]

We report on high-resolution laser spectroscopy studies on Cf249–253 with spectral linewidths in the order of 100 MHz carried out at the RISIKO mass separator at Mainz University. In total three atomic ground-state transitions were investigated and the hyperfine parameters for the odd-A isotopes and isotope shift for all examined isotopes have been determined from the measured spectra.

The Electron Capture in $^{163}$Ho Experiment - a Short Update

The definition of the absolute neutrino mass scale is one of the main goals of the Particle Physics today.
The study of the end-point regions of the $\beta$- and electron capture (EC) spectrum offers a possibility to determine the effective electron (anti-)neutrino mass in a completely model independent way, as it only relies on the energy and momentum conservation. [...]

CERN-MEDICIS: A Review Since Commissioning in 2017
/ MEDICIS Collaboration
The CERN-MEDICIS (MEDical Isotopes Collected from ISolde) facility has delivered its first radioactive ion beam at CERN (Switzerland) in December 2017 to support the research and development in nuclear medicine using non-conventional radionuclides. Since then, fourteen institutes, including CERN, have joined the collaboration to drive the scientific program of this unique installation and evaluate the needs of the community to improve the research in imaging, diagnostics, radiation therapy and personalized medicine.

Measurement of the laser resonance ionization efficiency for lutetium

The development of a highly efficient resonance ionization scheme for lutetium is presented. A laser ion source, based on the all-solid-state Titanium:sapphire laser system, was used at the 30 keV RISIKO off-line mass separator to characterize different possible optical excitation schemes in respect to their ionization efficiency.
