Název v původním jazyce

Laser-driven high-energy proton beam with homogeneous spatial profile from a nanosphere target

Popis výsledku v původním jazyce

A high-energy, high-yield proton beam with a good homogeneous profile has been generated from a nanosphere target irradiated by a short (30-fs), intense (7 x 10(20) W/cm(2)) laser pulse. A maximum proton energy of 30 MeV has been observed with a high proton number of 7 x 10(10) in the energy range 5-30 MeV. A homogeneous spatial profile with a uniformity (standard deviation from an average value within 85% beam area) of 15% is observed with the nanosphere dielectric target. Particle-in-cell simulationsshow the enhancement of proton cutoff energy and proton number with the nanosphere target and reveal that the homogeneous beam profile is related with a broadened angular distribution of hot electrons, which is initiated by the nanosphere structure. Thehomogeneous spatial properties obtained with the nanosphere target will be advantageous in developing laser-driven proton sources for practical applications in which high-quality beams are required.
