Demonstration of tunability of HOFI waveguides via start-to-end simulations
S. M. Mewes, G. J. Boyle, A. Ferran Pousa +7
In recent years, hydrodynamic optical-field-ionized (HOFI) channels have emerged as a promising technique to create laser waveguides suitable for guiding tightly-focused laser puls…
The Linear Collider Facility (LCF) at CERN
H. Abramowicz, E. Adli, F. Alharthi +406
In this paper we outline a proposal for a Linear Collider Facility as the next flagship project for CERN. It offers the opportunity for a timely, cost-effective and staged construc…
Technical Status Report on Plasma Components and Systems in the context of EuPRAXIA
A. Biagioni, N. Bourgeois, F. Brandi +27
The EuPRAXIA project aims to construct two state-of-the-art accelerator facilities based on plasma accelerator technology. Plasma-based accelerators offer the possibility of a sign…
Low-Density Hydrodynamic Optical-Field-Ionized Plasma Channels Generated With An Axicon Lens
R. J. Shalloo, C. Arran, A. Picksley +9
We demonstrate optical guiding of high-intensity laser pulses in long, low density hydrodynamic optical-field-ionized (HOFI) plasma channels. An axicon lens is used to generate HOF…
A Linear Collider Vision for the Future of Particle Physics
