Observation of MeV-ions in long pulse large-scale laser produced plasmas
PACS: 32.30.Rj, 52.25.Nr, 52.70.La
A new approach for the investigation of generation of fast ions and hot electrons inside the same plasma volume in laser produced plasmas is proposed. It is based on the spectroscopic observation of line radiation from single and double excited levels with simultaneous high spectral and spatial resolution. The experimental results demonstrate the observation of fast ions from highly charged target material inside the plasma volume and suggest that the generally accepted scaling relations are serious invalid under certain conditions. Even for rather modest intensities ions with several MeV-energy are observed.
