By means of space resolved X-ray spectroscopy we have investigated the generation of fast (up to MeV) ions for various laser installations with different flux densities (1012-1014W/cm2) and laser wavelengths (λ = 308 nm, 800 nm, 1.06 μm, 10.6 μm). The implementation of our spectroscopically determined data into the generally accepted scaling relation diagrams with the axes qλ2and Eion, where q is the laser flux density, λ the laser wavelength and Eionthe fast ion energy showed a large scatter by orders of magnitude. The simultaneous use of mass spectrometry showed reasonable agreement for both methods of measurements. Non-Maxwellian X-ray spectroscopy enabled us for the first time to investigate the generation of fast ions and hot electrons by means of space resolved spectroscopy in plasma areas, where the interaction with the laser beam takes place.
