Fig. 1.

Particle momentum distributions of three chosen typical simulations, for μ = 100, a˜1=0.25$${\mathop a\limits^ \sim _1} = 0.25$$, and the size = 46082 cells. The initial enthalpy ratio wi/we is indicated in each panel with a different color, so as to make it easier to compare with Fig. 2.

Fig. 3.

The left panel shows the dependence of qe on the initial enthalpy ratio wi/we. The middle and right panels compare the relative gains qe of the electron’s kinetic energies with the results of previous studies (dashed lines). The marker styles and colors are indicated in the figure.
