Title: High pressure radiant energy image furnace

Abstract: A high pressure radiant energy image furnace includes a radiant heat source, such as a Xenon short arc lamp or a halogen incandescent lamp, and an optical system for concentrating the radiant energy from the source on a sample enclosed in a thin wall transparent sample vessel. A closed high pressure vessel resistant to more than 10 atmospheres encloses the heat source as well as the optical system, sample and the sample vessel. A first high pressure gas source communicates with the high pressure vessel and a second high pressure gas source communicates with the sample vessel. The sample in the sample vessel is subjected to a gas pressure of more than 10 atmospheres and the gas pressures in the high pressure vessel and the sample vessel are substantially the same whereby pressure stresses the sample vessel created by differences in internal and external gas pressure are eliminated and the sample safety heated.
