Neutrons are powerful tools for investigating the structure and properties of materials used in
science and technology. Recently, laser-driven neutron sources (LDNS) have attracted the …

Using one of the world most powerful laser facility, we demonstrate for the first time that high-
contrast multi-picosecond pulses are advantageous for proton acceleration. By extending …

The high-energy petawatt PETAL laser system was commissioned at CEA's Laser
Mégajoule facility during the 2017–2018 period. This paper reports in detail on the first …

Using quantum electrodynamics particle-in-cell simulations, we optimize the gamma flare (γ-
flare) generation scheme from the interaction of a high power petawatt-class laser pulse with …

We measure nuclear and electron spin-polarized H and D densities of at least 10 19 cm− 3
with∼ 10 ns lifetimes, from the photodissociation of HBr and DI with circularly polarized UV …

Increasing the laser energy absorption into energetic particle beams represents a
longstanding quest in intense laser-plasma physics. During the interaction with matter, part …

The Lawson criterion for proton-boron (p-11B) thermonuclear fusion is substantially higher
than that for deuterium-tritium (DT) because the fusion cross section is lower and peaks at …

Relativistic electron temperatures were measured from kilojoule, subrelativistic laser-plasma
interactions. Experiments show an order of magnitude higher temperatures than expected …

The thermal and epithermal neutrons are powerful probes to inspect water or high-pressure
hydrogen gas because of their large scattering cross-sections with protons. Laser-driven …

The dependence of the mean kinetic energy of laser-accelerated relativistic electrons (REs)
on the laser intensity, so-called ponderomotive scaling, explains well the experimental …
