Laser ion acceleration in an overdone plasma with relativistic non-Maxwellian
electrons

The ion acceleration in a foil plasma irradiated by a high intensity laser has been studied by
applying a relativistic electromagnetic Particle-In-Cell code. The considered plasma contains non-
Maxwellian electrons. The presence of the initial non-Maxwellian electrons drastically affect the
excited charge-separation electric field, ion velocity, and the ion expansion (see Fig. 1). Moreover,
the results show that the presence of the initially non-Maxwellian electrons impress on the ion
energy spectrum different from the initially Maxwellian distribution.
