  1. 1. Investigation of Nuclear Materials with Positron Measurements

    Författare :Petty Bernitt Cartemo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; depth profiling; positron beam; nuclear materials; radiation damage; positron lifetime measurements;

    Sammanfattning : Positron Annihilation Lifetime Spectroscopy can be used to characterize radia- tion-induced material defects to subsequently optimize nuclear materials with respect to radiation damage. Nuclear Systems of the future such as Generation IV and fusion concepts demand high performance from structural materials, comprising a material's stability in highly-radiative and hot environments.
