Focusing dynamics of high-energy density, laser-driven ion beams.
The dynamics of the focusing of laser-driven ion beams produced from concave solid targets was studied. Most of the ion beam energy is observed to converge at the center of the cylindrical targets with a spot diameter of 30 μm, which can be very beneficial for applications requiring high beam energy densities. Also, unbalanced laser irradiation does not compromise the focusability of the beam....
متن کاملLaser-driven shock acceleration of monoenergetic ion beams.
We show that monoenergetic ion beams can be accelerated by moderate Mach number collisionless, electrostatic shocks propagating in a long scale-length exponentially decaying plasma profile. Strong plasma heating and density steepening produced by an intense laser pulse near the critical density can launch such shocks that propagate in the extended plasma at high velocities. The generation of a ...
متن کاملHigh-Flux Monochromatic Electron and Ion Beams from Laser Cooled Atoms
Sources of inherently cold electrons and ions have undergone rapid development in the past few years. These sources are based upon near-threshold ionization of laser cooled atoms, and show great promise for the creation of high-brightness ion beams, in particular, for use in focused ion beam systems [1, 2], as well as the creation of electron bunches suitable for ultrafast electron diffraction ...
متن کاملEfficient quasi-monoenergetic ion beams from laser-driven relativistic plasmas.
Table-top laser-plasma ion accelerators have many exciting applications, many of which require ion beams with simultaneous narrow energy spread and high conversion efficiency. However, achieving these requirements has been elusive. Here we report the experimental demonstration of laser-driven ion beams with narrow energy spread and energies up to 18 MeV per nucleon and ∼5% conversion efficiency...
متن کاملPrecision absolute positional measurement of laser beams.
We describe an instrument which, coupled with a suitable coordinate measuring machine, facilitates the absolute measurement within the machine frame of the propagation direction of a millimeter-scale laser beam to an accuracy of around ±4 μm in position and ±20 μrad in angle.
