Proton Beam Acceleration with Circular Polarized Laser Pulses*
Recently, radiation pressure acceleration (RPA) has been proposed and extensively studied, which shows circularly polarized (CP) laser pulses can accelerate mono-energetic ion bunches in a phase-stableacceleration (PSA) way from ultrathin foils. For appropriate parameters, CP pulses may accelerate foils as a whole with most of the transferred energy carried by ions. It is found that self-organi...
متن کاملDivergence control with optimized targets for laser proton acceleration
O. Deppert1, K. Harres1, F. Nürnberg1, G. Schaumann1, M. Schollmeier2, and M. Roth1 1Institut für Kernphysik, Technische Universität Darmstadt, Germany; 2Sandia National Laboratories, Albuquerque NM, USA The irradiation of thin metal foils by an ultra-intense, relativistic laser pulse leads to the generation of a highly laminar and intense proton beam accelerated from the target rear side by a ...
متن کاملProton acceleration by moderately relativistic laser pulses interacting with solid density targets
We use two-dimensional (2D) particle-in-cell simulations to study the interaction of short-duration, moderately relativistic laser pulses with submicrometric dense hydrogen plasma slabs. Particular attention is devoted to proton acceleration by the target normal sheath mechanism. We observed that improved acceleration due to relativistic transparency of the target is unlikely for the shortest p...
متن کاملIon Acceleration by Short Chirped Laser Pulses
Direct laser acceleration of ions by short frequency chirped laser pulses is investigated theoretically. We demonstrate that intense beams of ions with a kinetic energy broadening of about 1% can be generated. The chirping of the laser pulse allows the particles to gain kinetic energies of hundreds of MeVs, which is required for hadron cancer therapy, from pulses of energies in the order of 100...
متن کاملBoosting laser-ion acceleration with multi-picosecond pulses
Using one of the world most powerful laser facility, we demonstrate for the first time that high-contrast multi-picosecond pulses are advantageous for proton acceleration. By extending the pulse duration from 1.5 to 6 ps with fixed laser intensity of 1018 W cm-2, the maximum proton energy is improved more than twice (from 13 to 33 MeV). At the same time, laser-energy conversion efficiency into ...
