“…At present, contrasts at about 10 12 can be achieved experimentally 32 for amplified spontaneous emission (ASE) pulses at I ¼ 10 10 W/cm 2 . In order to model ASE and prepulse effects, we use a preplasma density profile obtained from hydrodynamic simulations.…”

Proton acceleration by ultra-intense laser pulse irradiating a target with cross-section smaller than the laser spot size and connected to a parabolic density channel is investigated. The target splits the laser into two parallel propagating parts, which snowplow the back-side plasma electrons along their paths, creating two adjacent parallel wakes and an intense return current in the gap between them. The radiation-pressure pre-accelerated target protons trapped in the wake fields now undergo acceleration as well as collimation by the quasistatic wake electrostatic and magnetic fields. Particle-in-cell simulations show that stable long-distance acceleration can be realized, and a 30 fs monoenergetic ion beam of >10 GeV peak energy and <2 divergence can be produced by a circularly polarized laser pulse at an intensity of about 10 22 W/cm 2 .

“…A further decrease of the thickness gives only spectra with lower proton number and maximum energy. However, this concept of decreasing target thickness and increasing laser contrast is an important route of today's research on laser ion acceleration, see (Henig et al, 2009) for example.…”

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.

“…At present, this is an active area of research. Up to now a substantial part of results has been obtained with relatively largescale, single-shot picosecond and sub-picosecond laser systems Snavely et al 2000;Fuchs et al 2006;Robson et al 2007;Henig et al 2009). However, for many applications a compact, repetitive ion source is necessary.…”
