Fig. 2. The energy depositions (solid lines) for the monoenergetic hot electrons with energies of 40 keV, 60 keV, and 100 keV. The density profile is shown as the dashed line.

Fig. 4. The energy deposition (blue line) and the locally deposited flux (red line) of the 100-keV monoenergetic hot electron in DT plasma.

Fig. 5. The gains versus the ignitor shock launching times. The black line represents LILAC calculations with the laser-driven shock ignition, and the colored lines are 1D simulations with the hot-electron-driven shock ignition with different hot-electron energies.

Fig. 6. The density and pressure profiles after the ignitor shock launched for 0, 100, and 200 ps. Panels (a)–(c) for the laser spike driven, and panels (d)–(f) for the hot-electron spike driven. The highest gain targets in Fig. 5 are utilized. For the laser-driven shock ignition, the ignitor shock launching time is 9.6 ns, and for the hot-electron-driven shock ignition, the ignitor shock launching time is 10.3 ns.
