The production of high-quality electron bunches in Laser Wake Field Acceleration [1] relies on the possibility to inject ultra-low emittance bunches in the plasma wave. A new bunch injection scheme (Resonant Multi-Pulse Ionization, ReMPI) has been conceived and studied in which electrons extracted by ionization are trapped by a large-amplitude plasma wave driven by a train of resonant ultrashort pulses [2]. Such a train of pulses can be obtained in very efficient, compact and stable way, by phase manipulation in the front-end [3]. The ReMPI injection scheme relies on currently available laser technology [4] and is being considered for implementation of future compact X-ray free electron laser schemes [5]. Simulations show that high-quality electron bunches with energy up tp 5 GeV, with normalized emittance below 0.1 mm◊mrad and energy spread below 1% can be obtained with a single stage.
