In case of practising X-ray stress measurement through a diffractometer, the Geiger tube slit must be moved from its normal position to the goniometer center by a displacement r, [numerical formula] R : The goniometer radius ψ : The angle between the specimen surface and a reflecting plane η : 90°-θ, θ : Bragg angle, to complete a focusing condition for any θ and ψ. By means of our automatic focusing apparatus made up of a set of simple link mechanism the Geiger tube slit could follow the newly made focusing circles for a half fixed angle ψ and a variable Bragg angle θ, and so all the points on the diffraction profile obtained could satisfy the focusing condition like a normal diffractometer. To test the accuracy of this method the macroscopic stress measurements were performed for various powder patterns, and satisfactory results were obtained.
