Experimental Research of Protons Generated Femtosecond Laser and Double Target Interaction at the Re

The energy distributions of the protons were studied at the target back normal direction generated by interaction of the femtosecond laser with 10 μm Cu and 5μm C8H8 double target.The CR39 solid state nuclear track detector combined with the thomson spectrum are used to measure the energy spectrum of the protons ment in the experiment.The results showed that the protons are emitted along the target rear-side normal direction and the proton beam was decreased with the increasing of proton energy....
