Abstract: An apparatus for making rapid in-situ thermal stress measurements includes a controlled atmosphere test chamber for receiving and holding a test sample, and a heating zone within the test chamber confined to the near vicinity of the test sample. A test sample holder, a test sample heater, an x-y translation stage and a rotating stage are mounted within the test chamber. An X-ray source is positioned for producing an incident X-ray beam directed at the test sample from different inclination angles. The incident X-ray beam passes through a long but narrow X-ray window in the test chamber, diffracts from the test sample back through the same X-ray window and continues outside of the chamber to an X-ray detector. The diffracted X-ray beam is converted to light. The light is transmitted through optical fibers and is detected by a CCD array. The invention uses an advantageous scintillation material and a slow scan, fiber-optic compatible CCD photo-sensor array.

Abstract: A method and apparatus for x-ray measurement of certain properties of a solid material. In distinction to known methods and apparatus, this invention employs a specific fiber-optic bundle configuration, termed a reorganizer, itself known for other uses, for coherently transmitting visible light originating from the scintillation of diffracted x-radiation from the solid material gathered along a substantially one dimensional linear arc, to a two-dimensional photo-sensor array. The two-dimensional photodetector array, with its many closely packed light sensitive pixels, is employed to process the information contained in the diffracted radiation and present the information in the form of a conventional x-ray diffraction spectrum. By this arrangement, the angular range of the combined detector faces may be increased without loss of angular resolution.
