Image of FIG. 1.
FIG. 1.

(a) Schematic of the gold-hollow plasma fiber around the low-density deuterium-tritium plasma. (b) The behavior of the beam electrons at . The thin dashed lines in (b) show the edges of the gold plasma. The trajectories of several typical electrons initially at show the propagation of the beam electrons in the plasma.

Image of FIG. 2.
FIG. 2.

(a) Normalized energy of the electric and magnetic fields. The insets (b) and (c) show the electric field at and 200 fs, respectively. The insets (d) and (e) show the corresponding magnetic fields. (f) Evolution of the trajectory of a typical beam electron and the magnetic field around it and (g) the corresponding power spectra.

Image of FIG. 3.
FIG. 3.

The beam-electron density , the magnetic field component (in megagauss), and the plasma electron temperature (in eV) at . The thin dashed lines in the subplots show the gold plasma and the thick solid lines in (a), (d), and (g) mark the electron density profile of the gold slab and the deuterium-tritium plasma in the beam propagation direction. The first, second, and third rows correspond to cases I, II, and III, respectively.
