Accelerated protons from near critical density gaseous targets

We report the generation of energetic protons from the interaction of an intense laser pulse with a near critical plasma density gaseous target. The target was formed by tailoring the gas flow of a hypersonic jet with externally generated hydrodynamic shocks. Configurations utilizing either a single...

Zusammenfassung:We report the generation of energetic protons from the interaction of an intense laser pulse with a near critical plasma density gaseous target. The target was formed by tailoring the gas flow of a hypersonic jet with externally generated hydrodynamic shocks. Configurations utilizing either a single or two colliding shocks were investigated. A 500mJ, 50 fs pulse from a Ti:Sapphire laser system was able to generate protons beams with energies
