Radiation Pressure Acceleration by Circularly Polarized Pulses: Three-Dimensional Dynamics and Angular Momentum Absorption — •Tatiana Liseykina1,2, Dieter Bauer1, Andrea Macchi3,4, Francesco Pegoraro3, and Sergei Popruzhenko1,51Max-Planck-Institut für Kernphysik, Heidelberg, Germany — 2Institute of Computational Technologies SD RAS, Novosibirsk, Russia — 3Physics Department, University of Pisa, Italy — 4PolyLAB, Pisa, Italy — 5Moscow Engineering Physics Institute, Russia

Radiation Pressure Acceleration of thin plasma targets by Circularly Polarized laser pulses is studied by three-dimensional particle-in-cell simulations. The use of flat-top intensity profiles is found to be important to avoid self-induced transparency and to reach high ion energies. A significant degree of absorption of the angular momentum of the laser pulse is observed, giving a signature of irreversible, non-adiabatic effects.
