[Formula: see text]Ac is a radio-isotope that can be linked to biological vector molecules treat certain distributed cancers using targeted alpha therapy. However, developing text]Ac-labelled radiopharmaceuticals remains challenge due the supply shortage of pure itself. Several techniques obtain are being investigated, amongst which high-energy proton spallation thorium or uranium combined with resonant laser ionization and mass separation. As proof-of-principle, we perform off-line...
The global electronic properties of solid-state devices are strongly affected by the microscopic spatial paths charge carriers. Visualising these in novel produced scalable processes would provide a quality assessment method that can propel device performance metrics towards commercial use. Here, we use high-resolution nitrogen-vacancy (NV) magnetometry to visualise flow gold-contacted, single-layer graphene methods. Modulating majority carrier type via field effect reveals strong asymmetry...
Laser spectroscopy in supersonic jets can reveal properties of short-lived nuclei. A new characterization jet flow determines the final performance a next-generation approach called in-gas-jet method.
Terbium-152 is one of four terbium radioisotopes that together form a potential theranostic toolbox for the personalised treatment tumours. As 152 Tb decay by positron emission it can be utilised diagnostics tomography. For use in radiopharmaceuticals and activity measurements an calibrator high radionuclide purity material accurate precise knowledge half-life required. Mass-separation radiochemical purification provide production route 152Tb. In current work, two mass-separated samples from...

This work presents the production cross-sections of Ce, Tb and Dy radionuclides produced by 300 MeV to 1.7 GeV proton-induced spallation reactions in thin tantalum targets as well related Thick Target Yield (TTY) values ratios. The motivation is optimise terbium for medical applications find out at which energy purity collection mass separation would be highest. For that purpose, activation experiments were performed using COSY synchrotron FZ Jülich utilising stacked-foils technique γ...
A study of the laser-ionized and mass-separated neutron-deficient isotopes $^{176,177,179}\mathrm{Au}$ was performed using Resonance Ionization Laser Ion Source Windmill detection setup at ISOLDE, CERN. New improved data on complex fine-structure $\ensuremath{\alpha}$ decays three were deduced, providing insight into low-lying levels in daughter nuclei $^{172,173,175}\mathrm{Ir}$. information properties $\ensuremath{\beta}$-decay products $^{177,179}\mathrm{Pt}$ also obtained. From first...
Abstract The CERN-MEDICIS facility aims to produce emerging medical radionuclides for the theranostics approach in nuclear medicine with mass separation of ion beams. To enhance radioisotope yield and purity collected samples, resonance ionization laser source MELISSA was constructed, provided first ions at 2019. Several operational tests were accomplished investigate its performance preparation upcoming production terbium radioisotopes, which are particular interest applications.
Abstract The presented paper discusses the production of radioactive ion beams francium, radium, and actinium from thick uranium carbide (UC x) targets at ISOLDE, CERN.
