High energy ion generation (energy in order of 10 Gev) have been estimated by interaction of picosecond laser pulses with an intensity of 6x1014 W/cm2 with metallic target in vacuum and gas atmosphere. In this paper we shall discuss the production of very high magnetic fields by flux compression in laser-induced plasmas and show experimental results on particle acceleration due to an explosively collapsed magnetic fields. Different nuclear track detectors have been used for heavy charged particle identification: synthetic mica, plastic nuclear detector CR-39, and glasses. Magnetic fields generated in laser-induced plasmas of order 30 -130 MGauss have been estimated by means of Faraday rotation and interferometric diagnostics with high temporal and spatial resolution.© (2010) COPYRIGHT SPIE--The International Society for Optical Engineering.
