Figure 16. 5: A Tokamak machine Figure 16.5: A Tokamak machine. Plasma is confined by a toroidal magnetic field. The toroid forms the secondary winding of a transformer. The current induced in the toroid is used for heating the plasma. Fig. 16-5, p. 537

Tiny gold microshells, similar to those containing high-pressure gaseous D–T fuel for use in laser fusion, on a U.S. quarter. p. 538

Figure 16.6: A fuel pellet of D–T is heated by laser radiation from all sides. It implodes as the surface explodes outward. Pressures on the order of a trillion atmospheres are achieved. Fig. 16-6, p. 539

Figure 16.7: The 60-beam OMEGA laser system is a 30,000 J ultraviolet laser. The fusion target chamber is to the left. Fig. 16-7, p. 540

Figure 16. 8: Schematic of a laser-fusion power plant Figure 16.8: Schematic of a laser-fusion power plant. Pellets of frozen D–T enter from the top. They are irradiated by laser beams. Lithium in the outer layer absorbs the energy released in fusion, and then turns water into steam in the heat exchangers. Fig. 16-8, p. 541
