Title: High pressure radiant energy image furnace
Claims: What I claim is: 1. A heating apparatus comprising a heat source including the arc of a Xenon short-arc lamp, an optical system for concentrating the radiant energy from said heat source on a sample to be heated, a thin wall sample vessel transparent to the radiant energy from said heat source and enclosing said sample air-tightly therein, a high pressure vessel resistible to more than 10 atmospheres and enclosing said heat source, said optical system, said sample and said sample vessel therein, a power supply cable passing air-tightly through the wall of said high pressure vessel for said heat source, a first high pressure gas source communicating with said high pressure vessel, and a second high pressure gas source communicating with said sample vessel, the sample in said sample vessel being subjected to a pressure of more than 10 atmospheres and the gas pressures in said high pressure vessel and said sample vessel being substantially the same, whereby pressure stresses on the sample vessel created by any difference in gas pressure inside and outside of the sample vessel are eliminated and the sample is safely heated. 2. A heating apparatus comprising a heat source including a radiant filament of a halogen incandescent lamp, an optical system for concentrating the radiant energy from said heat source on a sample to be heated, a thin wall sample vessel transparent to the radiant energy from said heat source and enclosing said sample air-tightly therein, a high pressure vessel resistible to more than 10 atmospheres and enclosing said heat source, said optical system, said sample and said sample vessel therein, a power supply cable passing air-tightly through the wall of said high pressure vessel for said heat source, a first high pressure gas source communicating with said high pressure vessel, and a second high pressure gas source communicating with said sample vessel, the sample in said sample vessel being subjected to a pressure of more than 10 atmospheres and the gas pressures in said high pressure vessel and said sample vessel being substantially the same, whereby pressure stresses on the sample vessel created by any difference in gas pressure inside and outside of the sample vessel are eliminated and the sample is safely heated.
