Electron energization during merging of self-magnetized, high-beta, laser-produced plasmas

Aug 5, 2021. Publications


Electron energization during merging of magnetized plasmas is studied using the OMEGA and OMEGA EP laser facilities by colliding two plasma plumes, each containing a Biermann-battery self-generated magnetic field. Two neighbouring plasma plumes are produced by intense laser beams, and the anti-parallel Biermann fields merge and reconnect in the process of the plumes’ expansion and collision. To isolate the merging as an acceleration source, the electron energy spectra obtained from two-plume collision shots are compared with the spectra from single-plume shots. Single-plume shots exhibit an energized electron tail with energies up to ∼250 keV. The electrons in merging experiments are additionally accelerated by ∼50--100 keV compared to single-plume shots.
