FIG. 3.

Opaque regime. Spatial distribution of high energy electrons at the target's back side with projected on to the plane obtained from a 3D simulation at (a)  = 20T ( > 0.05 MeV) and (c)  = 60T ( >1.5 MeV). (b) Electron distribution in the p-p phase space at  = 20T. (d) Intensity distribution of the laser electric field at at  = 20T in the plane.
