Abstract

We show the laser-driven acceleration of unprecedented, collimated (2 mrad 2 \ \mathrm{mrad} divergence), and quasi-monoenergetic (25 % 25 \ \% energy spread) electron beams with energy up to 50 MeV 50 \ \mathrm{MeV} at 1 kHz 1 \ \mathrm{kHz} repetition rate. The laser driver is a multi-cycle (15 fs 15 \ \mathrm{fs} ) 1 kHz 1 \ \mathrm{kHz} optical parametric chirped pulse amplification (OPCPA) system, operating at 26 mJ 26 \ \mathrm{mJ} (1.7 TW 1.7 \ \mathrm{TW} ). The scalability of the driver laser technology and the electron beams reported in this work pave the way towards developing high-brilliance x-ray sources for medical imaging, innovative devices for brain cancer treatment, and represent a step towards the realization of a kHz GeV electron beamline.
