Crossed-beam laser acceleration of ions by high-intensity laser fields — •Benjamin Galow, Zoltán Harman, Dunfu Shi, and Christoph H. Keitel — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, D-69029 Heidelberg, Germany

Simulations based on the coupled relativistic equations of motion show that an ensemble of ions stemming from laser-plasma acceleration processes can be post-accelerated using crossed pulsed laser beams focused to spot radii on the order of the laser wavelength. We demonstrate that the crossed beams produce monoenergetic accelerated particles of several hundred MeV/nucleon with small energy spreads and high densities as required for hadron cancer therapy.
