Modulation of laser-driven proton beams in underdense plasma
Particle-in-cell simulations have been carried out to investigate the behavior of pulsed proton beams accelerated by laser within underdense plasma. The results reveal that wakefields generated by the proton beam effectively focus the proton beam, improving the beams' spatial distribution and energy spread. Additionally, electron rotations, inspired by an external longitudinal magnetic field, form a transverse focusing field near the proton beam, by which the proton beam can be focused more effectively. This implies the possibility of utilizing plasma as a viable medium for transport and focusing laser-accelerated broadband-energy proton beams, offering solutions to preserve and improve the proton beam properties, which is crucial for a variety of applications of laser-accelerated proton beams.
