ABSTRACT
Particle-in-cell (PIC) simulation results of sustained acceleration of electron-positron (e+e-) plasmas by comoving electromagnetic (EM) pulses are presented. When a thin slab of overdense e+e- plasma is irradiated with linear-polarized ultra-intense short laser pulses from both sides, the pulses are transmitted when the plasma is compressed to thinner than ∼2 relativistic skin depths. A fraction of the plasma is then captured and efficiently accelerated by self-induced J×B forces. For 1 μm laser and 1021 W cm-2 intensity, the maximum energy exceeds GeV in a picosecond.
