Ultrafast Laser Driven Micro-Lens to Focus and Energy Select MeV Protons

Résumé

We present a technique for simultaneous focusing and energy selection of high-current, MeV proton beams using radial, transient electric fields (10 7-10 10 V/m) triggered on the inner walls of a hollow micro-cylinder by an intense, subpicosecond laser pulse. Due to the transient nature of the focusing fields, the proposed method allows selection of a desired range out of the spectrum of the polyenergetic proton beam. This technique addresses current drawbacks of laser accelerated proton beams, i.e. their broad spectrum and divergence at the source.
