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.

Hot electron enhanced photoemission from laser fabricated plasmonic photocathodes / Martinez-Calderon, Miguel (CERN) ; Groussin, Baptiste (CERN) ; Bjelland, Victoria (CERN ; Norwegian U. Sci. Tech.) ; Chevallay, Eric (CERN) ; Fedosseev, Valentin N (CERN) ; Himmerlich, Marcel (CERN) ; Lorenz, Pierre ; Manjavacas, Alejandro ; Marsh, Bruce A (CERN) ; Neupert, Holger (CERN) et al.
Photocathodes are key elements in high-brightness electron sources and ubiquitous in the operation of large-scale accelerators, although their operation is often limited by their quantum efficiency and lifetime. Here, we propose to overcome these limitations by utilizing direct-laser nanostructuring techniques on copper substrates, improving their efficiency and robustness for next-generation electron photoinjectors.

Resonant laser ionization and mass separation of $^{225}$Ac / Johnson, Jake D (Leuven U.) ; Heines, Michael (Leuven U.) ; Bruchertseifer, Frank (Geel, JRC) ; Chevallay, Eric (CERN) ; Cocolios, Thomas E (Leuven U.) ; Dockx, Kristof (Leuven U.) ; Duchemin, Charlotte (Leuven U. ; CERN) ; Heinitz, Stephan (SCK-CEN, Mol) ; Heinke, Reinhard (Leuven U. ; CERN) ; Hurier, Sophie (Leuven U. ; SCK-CEN, Mol) et al.
$^{225}$Ac is a radio-isotope that can be linked to biological vector molecules to treat certain distributed cancers using targeted alpha therapy. However, developing $^{225}$Ac-labelled radiopharmaceuticals remains a challenge due to the supply shortage of pure $^{225}$Ac itself. [...]

Mapping charge capture and acceleration in a plasma wakefield of a proton bunch using variable emittance electron beam injection / AWAKE Collaboration
In the Phase 2 of the AWAKE first experimental run (from May to November 2018), an electron beam was used to probe and test proton-driven wakefield acceleration in a rubidium plasma column. In this work, we analyze the overall charge capture and shot-to-shot reproducibility of the proton-driven plasma wakefield accelerator with various electron bunch injection parameters. [...]

The AWAKE Run 2 programme and beyond / AWAKE Collaboration
Plasma wakefield acceleration is a promising technology to reduce the size of particle accelerators. Use of high energy protons to drive wakefields in plasma has been demonstrated during Run 1 of the AWAKE programme at CERN. [...]

Challenges of Automating the Photocathode Fabrication Process at CERN / Charrondière, Cedric (CERN) ; Chevallay, Eric (CERN) ; Zilliox, Thomas (CERN)
The CERN Photoemission Laboratory was founded in 1989 with the goal of studying laser-driven electron sources, for producing high-brightness electron beams within the framework of the Compact Linear Collider (CLIC) study. To produce these photocathodes, two processes run in parallel. [...]

Efficient Production of High Specific Activity Thulium-167 at Paul Scherrer Institute and CERN-MEDICIS / Heinke, Reinhard (CERN ; Leuven U.) ; Chevallay, Eric (CERN) ; Chrysalidis, Katerina (CERN) ; Cocolios, Thomas E (Leuven U.) ; Duchemin, Charlotte (Leuven U. ; CERN) ; Fedosseev, Valentin N (CERN) ; Hurier, Sophie (Leuven U. ; SCK-CEN, Mol) ; Lambert, Laura (CERN) ; Leenders, Benji (Leuven U. ; SCK-CEN, Mol ; Gent U.) ; Marsh, Bruce A (CERN) et al.
Thulium-167 is a promising radionuclide for nuclear medicine applications with potential use for both diagnosis and therapy (“theragnostics”) in disseminated tumor cells and small metastases, due to suitable gamma-line as well as conversion/Auger electron energies. However, adequate delivery methods are yet to be developed and accompanying radiobiological effects to be investigated, demanding the availability of $^{167}$Tm in appropriate activities and quality.

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.
