Riassunto:  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 . 08 mm × mrad and 0.65% energy spread can be obtained with a single present-day 100T W-class Ti:Sa laser system.
