Generation of fast protons by interaction of modest laser intensities with H sub(2)O 'snow' nano-wire targets

Generation of fast protons by interaction of modest laser intensities with H sub(2)O 'snow' nano-wire targets

We report on the generation of protons with energies of 5.5 MeV when irradiating an H sub(2)O nano-wire layer grown on a sapphire plate with an intensity of 5x10 super(17) W/cm super(2). A theoretical model is suggested in which plasma near the tip of the wire is subject to enhanced electrical field...

Zusammenfassung:We report on the generation of protons with energies of 5.5 MeV when irradiating an H sub(2)O nano-wire layer grown on a sapphire plate with an intensity of 5x10 super(17) W/cm super(2). A theoretical model is suggested in which plasma near the tip of the wire is subject to enhanced electrical fields and protons are accelerated to several MeVs.
