Research Abstract

Irradiations of intense laser pulses on gas targets generate high energy charged particles, X-and gamma-rays, and negatively charged ions are also observed in recent experiments. In this study, we proposed Coulomb implosion mechanism which explains the acceleration mechanism of negative ions in laser-plasmas. We also proposed magnetic vortex acceleration, which is an efficient acceleration mechanism of positive ions from gas density plasmas. This mechanism enhances ion energy roughly ten-folds, which could contribute to development of compact laser-drive ion source.
