Energy spectra of escaped electron and proton beams obtained simultaneously using the Thomson parabola ion spectrometer and the magnetic electron spectrometer at different laser intensities. (a) Electron energy spectra shown with open rectangles and black dots are obtained at the and , which can be fitted with the slope temperatures of and , respectively, for Boltzmann distributions. The dashed line shows the detection limit. (b) Proton energy spectra obtained simultaneously with the escaped electron energy spectra of (a). The data points of open rectangles and black dots correspond to the data points at and , respectively, of (a). The proton energy spectra have the spectral cutoffs at maximum energies of and , respectively. The black solid line shows the detection limit.
