94. Ultrafast instabilities in shortpulse laser-solid interactions revealed by XFEL measurements and particle-in-cell simulations

Beam-plasma and laser-plasma interactions and acceleration

Oral presentation (preferred)

Ultra-intense lasers that ionize atoms and accelerate electrons in solids to nearly the speed of light can lead to kinetic instabilities that alter the laser absorption and subsequent electron transport, isochoric heating, and plasma expansion. These instabilities can be difficult to characterize, but a novel approach using X-ray scattering at keV photon energies allows for their visualization...

43. Ionizing Radiation from Laser Target Interactions: High Irradiance for SLAC MEC-U Project and Low Irradiance for Laser Material Processing

Sayed Rokni (SLAC National Accelerator Laboratory)

Beam-plasma and laser-plasma interactions and acceleration

Oral presentation (preferred)

Interaction of a high irradiance laser beam with matter creates a plasma on the target surface. The laser’s electric field accelerates charged particles in the plasma, and the accelerated charged particles can produce ionizing radiation hazards. The spectrum and dose rate of ionizing radiation depend on the laser irradiance at the target, the average laser power and the atomic number of the...

89. Source terms for the HED science in short-pulse experiments with solid target, and further perspectives

Beam-plasma and laser-plasma interactions and acceleration

Oral presentation (preferred)

In the facilities dedicated to the investigation of the matter under extreme conditions, without production of accelerated proton/ion or electron beams, the radiation protection assessment is primarily driven by the electron dynamics in the plasma. In the case of ultra-short relativistic laser pulses hitting a solid target, the radiation source term is given by the electrons escaping from the...

41. Status of the ELI Beamlines facility

Roberto Versaci (ELI ERIC)

Beam-plasma and laser-plasma interactions and acceleration

Oral presentation (preferred)

The Extreme Light Infrastructure (ELI) is the world largest and most advanced high-power laser infrastructure. It is established as a European Research Infrastructure Consortium since 2021. The Czech Republic, where the ELI Beamlines facility is located is a founding member of the Consortium of which the ELI Beamlines facility became integral part in 2023.
ELI Beamlines aims at the...

38. Shielding Design and Environmental Dose Monitoring for the ALFA Laser-Plasma Accelerator at ELI Beamlines

Dávid Horváth (ELI ERIC)

30/05/2024, 18:00

Beam-plasma and laser-plasma interactions and acceleration

Oral presentation (preferred)

As the commissioning of the laser systems at the ELI Beamlines Facility of ELI ERIC progresses, its laser-driven particle acceleration experiments reach ever higher energies and intensities. Due to the uncertainties in the laser-matter interaction and the variability of the experimental setup, the actual dose rate maps could differ from the results of the Monte Carlo simulations. This requires...
