ANGULAR CORRELATION POSITRON ANNIHILATION SPECTROMETER

Rudolf Gröne et al.

   In order to study some microstructural changes in irradiated nuclear reactor pressure vessel steels using a positron annihilation technique, a new three-detector set-up, suitable for a positron 1-Dimensional Angular Correlation of Annihilation Radiation (1D-ACAR) study of ⁶⁰Co - containing materials, was developed. The design of the equipment as well as results from test-measurements are described.

Keywords: positron annihilation, angular correlation, steel, reactor pressure vessel
