Relativistic acceleration of electrons injected by a plasma mirror into a radially polarized laser beam
N. Zaïm, M. Thévenet, A. Lifschitz +1
We propose a method to generate femtosecond, relativistic and high-charge electron bunches using few-cycle and tightly focused radially polarized laser pulses. In this scheme, the…
Vehicle detection and counting from VHR satellite images: efforts and open issues
Alice Froidevaux, Andréa Julier, Agustin Lifschitz +5
Detection of new infrastructures (commercial, logistics, industrial or residential) from satellite images constitutes a proven method to investigate and follow economic and urban g…
Energy-chirp compensation in laser wakefield accelerators
A. Döpp, C. Thaury, E. Guillaume +7
The energy spread in laser-wakefield accelerators is primarily limited by the energy-chirp introduced during the injection and acceleration processes. Here we propose and demonstra…
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…
High-charge relativistic electron bunches from a kHz laser-plasma accelerator
Dominykas Gustas, Diego Guénot, Aline Vernier +5
We report on electron wakefield acceleration in the resonant bubble regime with few-millijoule near-single-cycle laser pulses at a kilohertz repetition rate. Using very tight focus…
