Abstract
An apparatus and method for providing a specified amount of heat on a test specimen, a portion of a specimen, or multiple specimens, under space-like conditions. This system includes a vacuum chamber in which one or more test specimens are placed. This chamber is evacuated to the necessary vacuum. One or more external sources of high intensity light is used for providing the necessary temperature. One or more reflectors are used for concentrating the high intensity light. A fiber optic light guide is used for receiving concentrated light from the reflector. A port in the vacuum chamber wall is used so that the second end of the light guide can extend into the chamber so that light exiting the second end impinges on a selected area of the test specimen. A positioning apparatus is used for locating the second end of the light guide within the housing adjacent to vary the test specimen area subjected to the light. One or more temperature sensors is used on the test specimens for providing feedback to the temperature controlling system for controlling the amount of light input to the guide to achieve the desired temperature.
