Shock interactions between plasma jets from conical wire array Z-pinches and laser-produced plasma plume

Results in Physics, 2022
The interaction of a supersonic plasma jet outflow with a background laser-produced plasma plume is experimentally studied. The aim of these studies is to provide an experimental platform to study jet-ambient interactions in an environment relevant to ...

Ion acceleration by superintense laser-plasma interaction [PDF]

, 2013
Ion acceleration driven by superintense laser pulses is attracting an impressive and steadily increasing effort. Motivations can be found in the potential for a number of foreseen applications and in the perspective to investigate novel regimes as far as

Electromagnetic field growth triggering super-ponderomotive electron acceleration during multi-picosecond laser-plasma interaction [PDF]

Communications Physics, 2018
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intensity, so-called ponderomotive scaling, explains well the experimental results to date; however, this scaling is no longer applicable to multi ...

Off-harmonic optical probing of high intensity laser plasma expansion dynamics in solid density hydrogen jets

Scientific Reports, 2022
Due to the non-linear nature of relativistic laser induced plasma processes, the development of laser-plasma accelerators requires precise numerical modeling.

The effect of laser polarization on radiation reaction trapping of the electrons in ultra high power laser interaction with rarified plasma [PDF]

مجله علوم و فنون هسته‌ای, 2021
In ultra-high power laser interaction with plasma, quantum electrodynamics phenomena such as high energy photon emission by electrons, radiation reaction trapping, and anti-particle creation can affect the interaction mechanism.

Generation of highly-polarized high-energy brilliant γ-rays via laser-plasma interaction

, 2020
The generation of highly polarized high-energy brilliant γ-rays via laser–plasma interaction is investigated in the quantum radiation-reaction regime. We employ a quantum electrodynamics particle-in-cell code to describe spin-resolved electron dynamics ...

Plasma photonic spatiotemporal synchronization of relativistic electron and laser beams

Physical Review Accelerators and Beams, 2022
We present an ultracompact plasma-based method to measure spatial and temporal concurrence of intense electron and laser beams nonintrusively at their interaction point.
