Abstract: The production of high-quality electron bunches in Laser Wa
ke Field Acceleration relies on the
possibility to inject ultra-low emittance bunches in the pl
asma wave. In this paper we present a new
bunch injection scheme in which electrons extracted by ioni
zation are trapped by a large-amplitude
plasma wave driven by a train of resonant ultrashort pulses.
In the REsonant Multi-Pulse Ionization
(REMPI) injection scheme, the main portion of a single ultra
short (e.g Ti:Sa) laser system pulse is
temporally shaped as a sequence of resonant sub-pulses, whi
le a minor portion acts as an ionizing
pulse. Simulations show that high-quality electron bunche
s with normalized emittance as low as
0
