Ensuring the operational safety of the materials of your manufactured products, parts and installations, is time, resources and means consuming and still presents imprecision, uncertainty, and risks as soon as industries are acting in a reactive mode regarding the caracterization of the evolution of their materials under mechanical, thermical, electrical or photonic conditions over the time. Implementing a predictive mode of diagnosis and prediction at the atomic scale of your materials at their various stages of utilization by non-radioactive positron annihilation spectrometry in high vacuum saves time, resources and means, guarantees the accuracy, the certainty and miinimizes the risks.
