Simulation of Transverse Collisionless Jets in Laser Plasma Experiments

The paper presents the results of a laboratory experiment with detailed measurements of the dynamics and spatial structure of a plasma flow similar to astrophysical jets. For the first time in such experiments, the magnetic field component generated by a shear flow in a rarefied background plasma was measured. It was shown that it can be interpreted as an Alfvén wing. The drift electric field in the jet propagation region was also measured. All these findings confirm that the external magnetic field remains frozen into the plasma flow throughout its propagation over distances significantly exceeding the ion’s Larmor radius.
