FIG. 1.

Density maps and radial profiles of the precompressed targets considered. (a) Super-Gaussian density distribution of the spherical blob, and (b) density distribution taken from Fig. 8 of Ref. 29. is the distance from the ion source to the simulation box.

Minimum ignition energies of the target shown in Fig. 1(a) heated by carbon ions with Gaussian and Maxwellian energy distributions as a function of the mean kinetic energy per nucleon. The ignition energies corresponding to a Gaussian beam in an ideal isochoric fuel are also shown. The ion source-core distances are for the beams with Gaussian energy distributions and for the Maxwellian one.

Ion temperature and density maps of the target shown in Fig. 1(b) just after the end of the pulse (23 ps) and (b) when the burn wave is propagating (50 ps). The carbon ions have a mean energy of 400 MeV with . The total pulse energy is 12 kJ. Dashed circles show the initial position of the isocontour.

Image of FIG. 10.
FIG. 10.

Minimum ignition energies of an electron beam with mean kinetic energy of 1.6 MeV impinging on the target shown in Fig. 1(a). Cone-core distance is the distance between the left surface of the simulation box and the center of the super-Gaussian density distribution. The curves are labeled with the initial divergence half-angle of the relativistic electron beam.
