Investigation on the origin of hot electrons in laser plasma interaction at shock ignition intensities

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-12 (2023)

Abstract Shock Ignition is a two-step scheme to reach Inertial Confinement Fusion, where the precompressed fuel capsule is ignited by a strong shock driven by a laser pulse at an intensity in the order of $$10^{16}$$ 10 16 W/cm $$^2$$ 2 . In this rep

Characterization of hot electrons generated by laser–plasma interaction at shock ignition intensities

Publikováno v: Matter and Radiation at Extremes, Vol 8, Iss 6, Pp 065602-065602-16 (2023)

In an experiment carried out at the Prague Asterix Laser System at laser intensities relevant to shock ignition conditions (I > 1016 W/cm2), the heating and transport of hot electrons were studied by using several complementary diagnostics, i.e., Kα

Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-8 (2017)

Abstract Relativistic laser interaction with micro- and nano-scale surface structures enhances energy transfer to solid targets and yields matter in extreme conditions. We report on the comparative study of laser-target interaction mechanisms with wi

Publikováno v: Physical Review Research, Vol 2, Iss 3, p 033451 (2020)

We show that both the flux and the cutoff energy of protons accelerated by ultraintense lasers can be simultaneously increased when using targets consisting of thin layers of bundled nanochannels. Particle-in-cell simulations suggest that the propaga

Scientific Reports

The interaction of ultraintense laser pulses with solids is largely affected by the plasma gradient at the vacuum–solid interface, which modifies the absorption and ultimately, controls the energy distribution function of heated electrons. A microm
