Microcoulomb-level electron beam and multi-Joule hard X-rays driven by a high-efficiency laser-plasma accelerator
B. Mahieu, L. Ribotte, W. Cayzac +38
We report on the production of ultrahigh-charge relativistic electron beams and the development of a laser-wakefield acceleration platform at the LMJ facility. Making use of the ki…
Compton photons at the GeV scale from self-aligned collisions with a plasma mirror
Aimé Matheron, Jean-Raphaël Marquès, Vincent Lelasseux +34
With today's multi-petawatt lasers, testing quantum electrodynamics (QED) in the strong field regime, where the electric field exceeds the Schwinger critical field in the rest fram…
Femtosecond X-ray absorption spectroscopy in warm dense matter
Benoît Mahieu, Noémie Jourdain, Kim Ta Phuoc +5
Exploring and understanding ultrafast processes at the atomic level is a scientific challenge. Femtosecond X-ray Absorption Spectroscopy (XAS) is an essential experimental probing…
High-brilliance betatron gamma-ray source powered by laser-accelerated electrons
Julien Ferri, Sébastien Corde, Andreas Döpp +8
Recent progress in laser-driven plasma acceleration now enables the acceleration of electrons to several gigaelectronvolts. Taking advantage of these novel accelerators, ultra-shor…
3D printing of gas jet nozzles for laser-plasma accelerators
A. Döpp, E. Guillaume, C. Thaury +3
Recent results on laser wakefield acceleration in tailored plasma channels have underlined the importance of controlling the density profile of the gas target. In particular it was…
An all-optical Compton source for single-exposure X-ray imaging
A. Döpp, E. Guillaume, C. Thaury +8
All-optical Compton sources are innovative, compact devices to produce high energy femtosecond X-rays. Here we present results on a single-pulse scheme that uses a plasma mirror to…
