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.

Performance of laser patterned copper plasmonic photocathodes / Martinez-Calderon, M (CERN) ; Groussin, B (CERN) ; Bjelland, V (CERN ; Norwegian U. Sci. Tech.) ; Chevallay, E (CERN) ; Himmerlich, M (CERN) ; Lorenz, P (Unlisted, DE) ; Marsh, B (CERN) ; Neupert, H (CERN) ; Rossel, R (CERN) ; Wuensch, W (CERN) et al.
We study ultrafast laser surface nanopatterning as an alternative to improve the photo-emissive properties of metallic photocathodes. By tailoring the physical dimensions of these surface nanostructures, one can localize the optical field intensity and exploit plasmonic effects occurring in such nanostructures. [...]

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.

Mean transverse energy, surface chemical and physical characterization of CERN-made Cs-Te photocathodes / Jones, L B (Daresbury ; Cockcroft Inst. Accel. Sci. Tech.) ; Panuganti, H (CERN) ; Benjamin, C (Daresbury ; Warwick U.) ; Chevallay, E (CERN) ; Churn, H M (Daresbury ; Cockcroft Inst. Accel. Sci.

Sci. Tech. ; Liverpool U.)
Cesium telluride photocathodes are known to offer high quantum efficiencies under UV illumination combined with good lifetimes compared to other semiconductor photocathodes, making them very popular electron sources for particle accelerator applications. The development of photocathode preparation, characterization, and related expertise at a single accelerator laboratory can be challenging, expensive, and time consuming. [...]

Fabrication and rejuvenation of high quantum efficiency caesium telluride photocathodes for high brightness and high average current photoinjectors / Martinez-Calderon, M (CERN) ; Chevallay, E (CERN) ; Rossel, R E (CERN) ; Jones, L B (Daresbury) ; Zevi Della Porta, G (CERN) ; Marsh, B (CERN) ; Granados, E (CERN)
With their high quantum efficiency (QE) and excellent photoemissive properties, cesium telluride (Cs-Te) photocathodes are the current workhorse in the high average current electron accelerators around the globe. Their ability to generate high brightness and high charge electron beams has opened the doorway to numerous applications, including fundamental particle physics research, radiation therapy, high-energy physics experiments, and high repetition rate free-electron lasers (FELs).

Production of innovative radionuclides for medical applications at the CERN-MEDICIS facility / CERN-MEDICIS Collaboration
Since its commissioning in December 2017, the CERN-MEDICIS facility has been providing non-conventional radionuclides for research in nuclear medicine. Benefitting from decades of experience in the production of radioactive ion beams and in the mass separation process from the ISOLDE facility at CERN, MEDICIS quickly became a worldwide key player in the supply of novel medical isotopes dedicated to research in the fields of cancer imaging, diagnostics, and radiation therapy.
