Forward Peaking of Laser Induced Plasma Plume

This paper represents the results of forward peaking in ion flux distribution of laser induced plasma plume of Ag. Ion flux distribution of silver plasma was detected using SSNTDs (CR-39), detector were placed at different angles from the normal of the target. The bunch of ions was received by the detector at 0fl, which indicates the maximum concentration of ions along the normal of the target, which named as forward peaking. Cu substrate was irradiated by Al ions, while Al, substrate was irradiated by Cu ions. In both cases substrate was placed along the normal of the target. There was a circular damage of ions at the surface of both substrates, which exhibits the forward peaking in laser induced plasma ions.
