“…Note that the potential of charge separation for the spectral modulation of laser-accelerated ion beams had been identified in earlier works already (Tikhonchuk et al, 2005;Robinson et al, 2006). The confined TNSA scheme has been confirmed for the first time experimentally by our group Pfotenhauer et al, 2008). Several other techniques for the generation of monoenergetic ion beams have been developed.…”

Using state‐of‐the‐art high‐power laser systems, we are able to routinely generate extreme energy densities and focused light intensities in a controlled laboratory environment. During the interaction of these laser pulses with matter a plasma is generated that can both sustain and support huge electric fields. These can be used as a novel type of accelerator structure for electrons and ions having properties favorable for a large number of future applications.

“…Visions of reaching electron energies in the TeV [4] and even the PeV regime [5] have been published. While the ion beams in most experiments have exhibited extremely broad energy distributions, advanced target designs have been applied to achieve narrow energy distributions of protons and heavier ions [6][7][8][9] . The early, rapid developments have engendered much speculation about the use of laser-driven ions for fast ignition [10][11][12] and medical applications [13][14][15][16][17] .…”

Experiments have shown that the ion energy obtained by laser-ion acceleration can be optimized by choosing either the appropriate pulse duration or the appropriate target thickness. We demonstrate that this behavior can be described either by the target normal sheath acceleration model of Schreiber et al. or by the radiation pressure acceleration model of Bulanov and coworkers. The starting point of our considerations is that the essential property of a laser system for ion acceleration is its pulse energy and not its intensity. Maybe surprisingly we show that higher ion energies can be reached with reduced intensities.

“…8). The simulations suggest that the beam quality in current experiments [27] could be dramatically improved by choosing microdot compositions with a 5-10 times lower proton fraction. Further investigations have further quantified these findings, setting lower limits on the useful proton fraction, beyond which an energy filtering scheme becomes more effective [28].…”

The recent developments in mesh-free plasma modeling using parallel tree codes are described, covering the algorithmic and performance issues and how to apply this technique to multidimensional electrostatic plasma problems. Examples of the simulations of the ion acceleration by high-intensity lasers, heating, and the dynamics of the nanostructured targets, as well as more recent applications of this technique to the simulations of edge plasmas in tokamaks and mesh-free magnetoinductive models, are given.
