The caesiated surface negative ion source is the first element of CERN's LINAC4 a linear injector designed to accelerate negative hydrogen ions to 160 MeV. The IS03 ion source is o…
Interaction of two Rydberg atoms in the vicinity of an optical nanofibre
E. Stourm, M. Lepers, J. Robert +3
We consider two rubidium atoms, prepared in the same S or P Rydberg states near an optical nanofibre. We determine the van der Waals interaction between them and identify novel fea…
Optical force between two coupled identical parallel optical nanofibers
Fam Le Kien, Sile Nic Chormaic, Thomas Busch
We study the optical force between two coupled parallel identical nanofibers using the rigorous array mode theory. We show that the forces of the even array modes are attractive, w…
Rubidium atom spectral lineshapes in high intensity electric fields near an optical nanofibre
Vandna Gokhroo, Fam Le Kien, Síle Nic Chormaic
The integration of cold atomic systems with optical nanofibres is an increasingly important experimental platform. Here, we report on the spectra observed during a strongly driven,…
European Strategy for Particle Physics -- Accelerator R&D Roadmap
C. Adolphsen, D. Angal-Kalinin, T. Arndt +133
The 2020 update of the European Strategy for Particle Physics emphasised the importance of an intensified and well-coordinated programme of accelerator R&D, supporting the design a…
Ionized particle transport in reactive HiPIMS discharge: correlation between the energy distribution functions of neutral and ionized atoms
Abderzak El Farsy, Dimitri Boivin, Cédric Noel +4
We investigated the transport titanium ions produced in a reactive high-power impulse magnetron sputtering (HiPIMS) device used for TiN coating deposition. Time-resolved mass spect…
On the electron energy distribution function in the high power impulse magnetron sputtering discharge
Martin Rudolph, A. Revel, D. Lundin +6
We apply the Ionization Region Model (IRM) and the Orsay Boltzmann equation for ELectrons coupled with Ionization and eXcited states kinetics (OBELIX) model to study the electron k…

A simplified and straightforward methodology that may be used to measure N(4 S) density by TALIF technique in strongly emissive plasmas is presented. The method makes use of the ab…
Post-corona unipolar chargers with tuneable aerosol size-charge relations: Parameters affecting ion dispersion and particle trajectories for charger designs
N. Jidenko, A. Bouarouri, F. Gensdarmes +3
This paper focusses on the mean charge per particle of monodisperse submicron aerosol, charged by diffusion of unipolar ions in post-corona discharge. It aims to confirm and discus…
Breaking simple quantum position verification protocols with little entanglement
Andrea Olivo, Ulysse Chabaud, André Chailloux +1
Instantaneous nonlocal quantum computation (INQC) evades apparent quantum and relativistic constraints and allows to attack generic quantum position verification (QPV) protocols (a…
Electron Sources from Plasmas
