Resumen
In this work, particle-in-cell simulations were carried out
to investigate the role of the down-ramp length of a H2 gas
jet in accelerating electrons ionized by the laser pulse. The
laser and plasma density were chosen so that the system is
operating in the self-modulated regime. Preliminary results
show how the down-ramp length can control the injection
of electrons in the first bubble induced in the plasma by the
laser pulse.
