Optimizing laser-driven proton acceleration from overdense targets
We demonstrate how to tune the main ion acceleration mechanism in laser-plasma interactions to collisionless shock acceleration, thus achieving control over the final ion beam properties (e. g. maximum energy, divergence, number of accelerated ions). We investigate this technique with three-dimensional particle-in-cell simulations and illustrate a possible experimental realisation. The setup co...

متن کاملLaser-Driven Ion Acceleration from Plasma Micro-Channel Targets
Efficient energy boost of the laser-accelerated ions is critical for their applications in biomedical and hadron research. Achiev-able energies continue to rise, with currently highest energies, allowing access to medical therapy energy windows. Here, a new regime of simultaneous acceleration of ~100 MeV protons and multi-100 MeV carbon-ions from plasma micro-channel targets is proposed by usin...

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 کاملIntense laser-driven electrostatic shocks and its acceleration of ions in overdense plasmas
We investigated numerically the formation and propagation of the electrostatic shocks in overdense plasmas irradiated by intense ultrashort laser pulses. The dependence of the initial shock speeds on the parameters of the plasma and the laser is explained by invoking the modified momentum conservation model. The acceleration of ions by the shocks is also discussed.
