At CERN-ISOLDE, high-purity radioactive ion beams of $^{219}$Fr and $^{221}$RaF were investigated with $\alpha$-decay spectroscopy at the CRIS and ASET experiments in the course of three different experimental campaigns. The half-life of $^{215}$At, $\alpha$-decay daughter of $^{219}$Fr, is measured to be 36.3(3)[9]μs, and that of $^{221}$Ra was determined to be 26.2(1)[6]s, both of which are well in line with the trends in this region of the nuclear landscape but at odds with some of the reported literature..

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.

Radio-frequency (RF) ion guides, also known as Linear Paul Traps, are powerful devices to efficiently transport ion beams from high to low pressure regions while keeping good ion optical properties. A set of ion guides comprising three different RF quadrupole (RFQ) structures has been designed using ion-trajectory simulations to improve the performance of the In-Gas Laser Ionizations and Spectroscopy (IGLIS) technique currently under development at KU Leuven.

This work reports the production cross-section data for seventy-one radionuclides produced by 0.3 GeV–1.7 GeV protons impinging on thin tantalum targets. For that purpose, activation experiments were performed using the COSY synchrotron at FZ Jülich utilizing the stacked-foils technique and γ-ray spectrometry with high-purity germanium detectors.
