The problems associated with miniaturization of the goniometer are discussed from the viewpoint of the stress error caused by mis setting of the specimen and misalignment of the collinator nad detector for the Ωassembly X-ray stress analyzer using a position sensitive detector. The sress eroers were calcutated using a model and a simulation medhod. It was found that they tend to increase with the decrease in goniometer fudius and collimator effective length. Therefore, the minimum size of the analyzer was investigated for a given value fo total error. In conclusion, it is believed that the size for the goniometer radius and the collimator effective length could possibly be pitomized. For the total stress error of about 40MPa in the case of stress measurement of a ferritic steel using Cr target, a set of the goniometer of 30mm in radius and the collimator of 30mm in effective length and 0.5mm in width could be a minimum size of the analyzer.
