A two-layer (layers 1 and 2) target configuration with plasma density and , respectively.
The net current density in the -direction (in ) at 156 fs: (a) for case I and (b) case II. The corresponding magnetic fields (in MG): (c) case I and (d) case II.
The net current density in the -direction (in ) at 156 fs: (a) for case III and (b) for case IV. The magnetic fields (in MG) that corresponds to (a) is shown in (c) and that of (b) in (d).
The average interface magnetic field (in MG) vs the density difference .
Trajectories of test electrons (1 and 2) with different initial momentum and angles in the magnetic field.
The collimation of test electrons (normalized) vs time. The solid line and the dashed and dot lines correspond to the cases , 10, and 1 MG, respectively.
The intense laser-driven fast electron density profile (in ) at . (a) Case VII and (b) case VIII. (c) The four curves show the normalized distribution of fast electrons in the transverse direction (the -direction) at for cases VII and VIII. The two dashed lines show the interfaces in case VII.
