Fig. 1. (a) Schematic of experimental setup and views of detectors. (b) Design and dimensions of solid hohlraum. (c) Design and dimensions of foam hohlraum. (d) Distribution of laser spots on hohlraum wall.

Fig. 2. (a) and (b) Experimental X-ray emission images from foam and solid hohlraums, respectively, between 1 and 2.4 ns. (c) and (d) Simulated X-ray emission images from foam and solid hohlraums, respectively, between 1 and 2.4 ns. (e) Variations in position of emission front with time. The experimental results for the foam and solid hohlraums are shown by the red triangles and black circles, respectively, with the corresponding simulated results being shown by the red dashed and black solid lines.

Fig. 3. (a) Hohlraum radiation temperatures at 3 ns at five different angles. Blue squares show the temperature of the solid hohlraum, and red rhombuses that of the foam hohlraum. (b) and (c) Temperature variations with time at angles of 0° and 64°, respectively.

Fig. 4. Radial distributions of electron density and temperature at t = 1 ns (a), 1.5 ns (b), 1.8 ns (c), and 2.4 ns (d) for the solid hohlraum (solid lines) and the foam hohlraum (dashed lines).

Fig. 5. Radial spatial distribution of X-ray emission between 0.8 and 1.2 keV at 1, 1.2, 1.5, 1.8, and 2 ns. Solid lines are for the solid hohlraum and dashed lines for the foam hohlraum.
