7 Jul 2016 | | Abstract: | Using two-dimensional particle-in-cell simulations, we examine how an
externally applied strong magnetic impacts proton acceleration in
laser-irradiated solid-density targets. We find that a kT-level external
magnetic field can sufficiently inhibit transverse transport of hot electrons
in a flat laser-irradiated target. While the electron heating by the laser
remains mostly unaffected, the reduced electron transport during proton
acceleration leads to an enhancement of maximum proton energies and the overall
number of energetic protons. The resulting proton beam is much better
collimated compared to a beam generated without applying a kT-level magnetic
field. A factor of three enhancement of the laser energy conversion efficiency
into multi-MeV protons is another effect of the magnetic field. The required kT
magnetic fields are becoming feasible due to a significant progress that has
been made in generating magnetic fields with laser-driven coils using ns-long
laser pulses. The predicted improved characteristics of laser-driven proton
beams would be critical for a number of applications. | | Source: | arXiv, 1607.1868 | | Services: | Forum | Review | PDF | Favorites | |
