Název v původním jazyce

Protons accelerated in the target normal sheath acceleration regime by a femtosecond laser

Popis výsledku v původním jazyce

Advanced targets based on thin films of graphene oxide covered by metallic layers have been irradiated at high laser intensity (similar to 10(19) W/cm(2)) with 40 fs laser pulses to investigate the forward ion acceleration in the target normal sheath acceleration regime. A time-of-flight technique was employed with silicon-carbide detectors and ion collectors as fast on-line plasma diagnostics. At the optimized conditions of the laser focus position with respect to the target surface was measured the maximum proton energy using Au metallic films. A maximum proton energy of 2.85 MeV was measured using the Au metallization of 200 nm. The presence of graphene oxide facilitates the electron crossing of the foil minimizing the electron scattering and increasing the electric field driving the ion acceleration. The effect of plasma electron density control using the graphene oxide is presented and discussed.
