The new LWFA ALFA beamline will be introduced, based on the ELI Beamlines’s in-house developed multi-cycle (15 fs) 1 kHz OPCPA power-scalable laser system. Recent results show the acceleration of collimated (few mrad divergence), quasi-monoenergetic electron beams with record breaking peak energy in the tens of MeV at 1 kHz repetition rate. These last could enable innovative medical applications.
