Front and rear side x-ray emission from thin titanium foils irradiated by ultraintense laser pulses at intensities up to approximate to 5 x 10(19) W/cm(2) was measured using a high-resolution imaging system. Significant differences in intensity, dimension, and spectrum between front and rear side emission intensity in the 3-12 keV photon energy range was found even for 5 mu m thin Ti foils. Simulations and analysis of space-resolved spectra explain this behavior in terms of directional bremsstrahlung emission from fast electrons generated during the interaction process.

Abstract
Front and rear side x-ray emission from thin titanium foils irradiated by ultraintense laser pulses at intensities up to approximate to 5 x 10(19) W/cm(2) was measured using a high-resolution imaging system. Significant differences in intensity, dimension, and spectrum between front and rear side emission intensity in the 3-12 keV photon energy range was found even for 5 mu m thin Ti foils. Simulations and analysis of space-resolved spectra explain this behavior in terms of directional bremsstrahlung emission from fast electrons generated during the interaction process.File in questo prodotto:
