Figure 5
Electron energy spectra. The total energy electron spectra as well as parallel and perpendicular components are plotted out in maroon lines, red squares and black circles, respectively. (a) \([\bar{{\mathscr{Z}}}=1]\) plasma and W0 = 3 μm; (b) \([\bar{{\mathscr{Z}}}=1]\) plasma and W0 = 15 μm; (c) \([\bar{{\mathscr{Z}}}=\frac{1}{3}]\) plasma and W0 = 3 μm; (d) \([\bar{{\mathscr{Z}}}=\frac{1}{3}]\) plasma and W0 = 15 μm. The spectra have been considered at the time corresponding to the maximum synchrotron radiation emission (t = tγ), i.e., t = 17 TL, 20 TL, 16 TL and 17 TL respectively. The parallel and perpendicular component of the temperature are defined compared with the direction of the laser wave propagation, i.e., the x axis.
