Abstract
1492572 Thermonuclear fusion FMS FUSION Inc 21 Nov 1974 50599/74 Heading G6P A thermonuclear fuel pellet for use in a laser fusion process comprises a hollow glass, ceramic, metal, or plastics microsphere containing thermonuclear fuel in the form of at least one hydrogen isotope. Preferably the pressure in the microsphere at room temperature is from 10 to 100 atmospheres. Hollow high-silica glass microspheres may be formed by passing a gas stream containing pulverized glass through a hot zone. A selected size range of these microspheres is heated under pressure with deuterium or a mixture of deuterium and tritium. After a period during which the gas diffuses into the interior of the microspheres, the temperature is lowered and the pressure reduced. The filled microspheres may be coated with a lead or bismuth glass, a soda-lime glass, copper, or aluminium. The fuel pellets may be stored at low temperature. On cooling in liquid nitrogen, CO 2 and H 2 O impurities form a solid layer on the inner surface of the microspheres, and at a lower temperature, the hydrogen isotopes themselves solidify in the same way.
