Studies Conducted at Institute of Applied Physics and Computational Mathematics on Nanowires Recently Reported (Enhanced Proton Acceleration From Laser Interaction With Curved Surface Nanowire Targets)

Article Description

A novel curved surface nanowire target is proposed to improve the cutoff energy of accelerated protons via target normal sheath acceleration. The interaction of a laser of intensity 1.37 × 1020 W cm-2 with a curved surface nanowire target is studied by two-dimensional particle-in-cell simulations. The numerical results indicate that the sheath electric field at the target rear side is significantly enhanced by this simple target design, compared with using the planar nanowire target. The transverse motion of hot electrons is effectively confined and the energy density of electrons is naturally increased. A series of simulations with various target parameters is carried out to investigate the performance of this novel target. This tailored target may provide implications for generating high-quality proton beams in experiments.
