Laser plasma proton acceleration experiments using foam-covered and grating targets
Original language description
Experimental results are reported for two different configurations of laser driven ion acceleration using solid foils with a structured layer on the irradiated side, aiming to improve the laser-target coupling by exploiting engineered surfaces. Two experimental campaigns have been performed exploiting a 100TW 25fs Ti:Sa laser capable of maximum intensity of 4 . 1019 W/cm2. ?Grating? targets have been manufactured by engraving thin mylar foils (0.9, 20 and 40 ?m) with a regular modulation having 1.6 ?m period and 0.5 ?m depth. The periodicity of the grating corresponds to a resonant incident angle of 30° for the excitation of surface waves. Considering a target of 20 ?m and changing the angle of incidence from 10° to 45°, a broad maximum in the proton energy cut-off was observed around the resonant angle (about 5 MeV) which was more than a factor two higher than the case of planar target. ?Foam? targets have been manufactured by depositing a porous 10 ?m nanostructured carbon film with
