Table-top laser-plasma ion accelerators seldom achieve narrow energy spreads, and never without serious compromises in efficiency, particle yield, etc. Using massive computer simulations, we identify a self-organizing scheme that exploits persisting self-generated plasma electric (~TV/m) and magnetic (~10${}^{4}$ Tesla) fields to reduce the ion energy spread after the laser exits the plasma - separating the ion acceleration from the energy spread reduction. Consistent with the scheme, we…

MeV Argon ion beam generation with narrow energy spread

Laser driven particle acceleration has shown remarkable progresses in generating multi-GeV electron bunches and 10s of MeV ion beams based on high-power laser facilities. Intense laser pulse offers

Uniform heating of materials into the warm dense matter regime with laser-driven quasimonoenergetic ion beams.

T theoretical calculations are presented that suggest the gold and diamond were heated uniformly by these laser-driven ion beams at Trident, with a finite energy spread of ΔE/E∼20%, which are expected to heat the targets more uniformly than a beam of 140-MeV aluminum ions with zero energy spread.

Visualization of expanding warm dense gold and diamond heated rapidly by laser-generated ion beams

A beam of quasi-monoenergetic aluminum ions is used to heat gold and diamond foils uniformly and isochorically to allow for direct quantitative measurements of equation-of-state, conductivity, opacity, and stopping power of warm dense matter, benefiting plasma physics, astrophysics, and nuclear physics.

Laser acceleration of quasi-monoenergetic MeV ion beams

Quasi-monoenergetic laser-driven C5+ ions with a vastly reduced energy spread are reported, which may enable significant advances in the development of compact MeV ion accelerators, new diagnostics, medical physics, inertial confinement fusion and fast ignition.

Electron, photon, and ion beams from the relativistic interaction of Petawatt laser pulses with solid targets

In recent Petawatt laser experiments at Lawrence Livermore National Laboratory, several hundred joules of 1 μm laser light in 0.5–5.0-ps pulses with intensities up to 3×1020 W cm−2 were incident on

Stable GeV ion-beam acceleration from thin foils by circularly polarized laser pulses.

It is shown for the first time by 2D simulations that high-density monoenergetic ion beams with energy above GeV/u and divergence of 10 degrees are produced by circularly polarized lasers at intensities of 10;{22} W/cm;{2}, which are within reach of current laser systems.

Ultralow emittance, multi-MeV proton beams from a laser virtual-cathode plasma accelerator.

The laminarity of high-current multi-MeV proton beams produced by irradiating thin metallic foils with ultraintense lasers has been measured and appears to be at least 100-fold better than conventional accelerator beams.

Collimated multi-MeV ion beams from high-intensity laser interactions with underdense plasma.

2D particle-in-cell simulations show that the ions are accelerated by a sheath electric field that is produced at the back of the gas target, which exits the target generating large space-charge fields normal to its boundary.

High-energy short-pulse lasers are pushing the limits of plasma-based particle acceleration, x-ray generation, and high-harmonic generation by creating strong electromagnetic fields at the laser

Reliable and reproducible laser-accelerated ion beams were achieved by intense laser irradiation of solid microstructured targets and Scalability studies show that, owing to their compact size and reasonable cost, such table-top laser systems with high repetition rates could contribute to the development of new generations of particle injectors that may be suitable for medical proton therapy.

Laser-driven shock acceleration of monoenergetic ion beams.

It is shown that monoenergetic ion beams can be accelerated by moderate Mach number collisionless, electrostatic shocks propagating in a long scale-length exponentially decaying plasma profile and that it is possible to generate ~200 MeV proton beams with state-of-the-art 100 TW class laser systems.

Ion acceleration in multispecies targets driven by intense laser radiation pressure.

The spectral features provide evidence of a multispecies scenario of radiation pressure acceleration in the light sail mode and indicates that monoenergetic peaks with more than 100 MeV/nucleon are obtainable with moderate improvements of the target and laser characteristics, which are within reach of ongoing technical developments.
