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.

In‐Source High‐Resolution Spectroscopy Using an Integrated Tunable Raman Laser / Granados, Eduardo (CERN) ; Stoikos, Georgios (CERN) ; Bernerd, Cyril (CERN) ; Chrysalidis, Katerina (CERN) ; Echarri, Daniel T (CERN) ; Fedosseev, Valentin N (CERN) ; Heinke, Reinhard (CERN) ; Marsh, Bruce A (CERN)
Tunable single-frequency lasers are the most prominent tool for high-resolution spectroscopy, allowing for the study and exploitation of the electronic structure of atoms. A significant milestone relies on the demonstration of integrated laser technology for performing such a task. [...]

First on-line application of the high-resolution spectroscopy laser ion source PI-LIST at ISOLDE / Heinke, Reinhard (CERN) ; Au, Mia (CERN ; Mainz U.) ; Bernerd, Cyril (CERN ; Leuven U.) ; Chrysalidis, Katerina (CERN) ; Cocolios, Thomas E (Leuven U.) ; Fedosseev, Valentin N (CERN) ; Hendriks, Isabel (CERN ; Lund U. (main)) ; Jaradat, Asar A H (CERN) ; Kaja, Magdalena (Mainz U., Inst. Phys.) ; Kieck, Tom (Darmstadt, GSI ; Helmholtz Inst., Mainz) et al.
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. [...]

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. [...]

Spectral synthesis of multimode lasers to the Fourier limit in integrated Fabry–Perot diamond resonators / Granados, Eduardo (CERN) ; Granados, Camilo ; Ahmed, Rizwan (CERN) ; Chrysalidis, Katerina (CERN) ; Fedosseev, Valentin N (CERN) ; Marsh, Bruce A (CERN) ; Wilkins, Shane G (CERN) ; Mildren, Richard P (Macquarie U.) ; Spence, David J (Macquarie U.)
Fourier-limited nanosecond pulses featuring narrow spectral bandwidths are required for applications in spectroscopy, sensing, and quantum optics. Here, we demonstrate a direct and simple route for the generation of single-frequency light relying on phonon-resonant Raman interactions within a monolithic diamond resonator. [...]

Enabling the use of Raman lasers for spectroscopy: continuous tunability, narrow linewidth and efficient cascading in diamond / Echarri, Daniel T (CERN ; Navarra U.) ; Chrysalidis, Katerina (CERN) ; Fedosseev, Valentin N (CERN) ; Marsh, Bruce A (CERN) ; Mildren, Richard P (Macquarie U.) ; Olaizola, Santiago M (Navarra U.) ; Spence, David J (Macquarie U.) ; Wilkins, Shane G (CERN) ; Granados, Eduardo (CERN)
We demonstrate a Raman laser continuously tunable in the visible range, capable of performing element-selective photo-ionization. The Stokes outputs exhibited a linewidth of 11.0 ± 1.0 GHz with a conversion efficiency of more than 60%..

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.
