Collisionless shocks are ubiquitous in the Universe. Charged particles can be accelerated to high energies by collisionless shock waves in astrophysical environments, such as supernova remnants. The internship is part of an ongoing effort of investigating laser-produced collisionless shocks in a magnetic field of tens of Tesla, both experimentally with high-power lasers worldwide, e.g., LULI2000 (FR), VULCAN (UK), and TITAN (US); and numerically with fully kinetic particle-in-cell simulations performed with the code SMILEI [4]. During the internship, the student will contribute to: - Experimental data analysis (e.g., energy spectrum of the energetic ions from Thomson parabola, the electromagnetic field structures from proton radiographs, and the plasma condition characterization from Thomson scattering). - Numerical simulations of the collision of two magnetized shocks, particularly tracking the charged particles and digging into their energization mechanism.
