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.
