US Patent:

44534230, Jun 12, 1984

Filed:

May 6, 1982

Appl. No.:

6/375645

Inventors:

Fred J. Fulton - Livermore CA
Charles A. Honodel - Tracy CA
William R. Holman - Danville CA
Richard C. Weingart - Livermore CA

Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC

International Classification:

G01N 128

US Classification:

73863

Abstract:

A method and apparatus for generating a measurable natural crack includes forming a primary notch in the surface of a solid material. A non-sustained single pressure pulse is then generated in the vicinity of the primary notch, resulting in the formation of a shock wave which travels through the material. The shock wave creates a measurable natural crack within the material which extends from the primary notch. The natural crack formed possesses predictable geometry, location and orientation.

International Classification:

B29D 2700

US Classification:

156 80

Abstract:

Foam-encapsulated laser fusion targets are fabricated by suspending fusion fuel filled shells in a solution of cellulose acetate, extruding the suspension through a small orifice into a bath of ice water, soaking the thus formed shell containing cellulose acetate gel in the water to extract impurities, freezing the gel, and thereafter freeze-drying wherein water and solvents sublime and the gel structure solidifies into a low-density microcellular foam containing one or more encapsulated fuel-filled shells. The thus formed material is thereafter cut and mounted on a support to provide laser fusion targets containing a fuel-filled shell surrounded by foam having a thickness of 10 to 60. mu. m, a cell size of less than 2. mu. m, and density of 0. 08 to 0. 6. times. 10. sup. 3 kg/m. sup. 3.
