The Application of a Position-Sensitive X-Ray Detector to the Measurement of Residual Stresses.
Abstract
In recent years considerable success has been achieved in the development of detectors for the localization of ionizing radiation. One dimensional position sensitive detectors have a number of uses in nuclear physics and in biological studies using small-angle scattering. Detectors are now capable of providing position information of high resolution with a high count rate capability and a simple read-out system. The authors report on the feasibility of employing a position sensitive proportional counter (PSPC) for the measurement of residual stresses with X-says. The ability of obtaining the entire profile at once is somewhat offset by the lower efficiency of the PSPC when compared to a scintiallation detector, but this is counteracted by the fact that motion of the detector is eliminated with the PSPC. It will be shown that a PSPC system provides a speed of data accumulation currently not available in any other way, while still remaining a versitile and accurate method.
