Influence of interference signals on spectrometer and measurement results in positron annihilation lifetime measurements

BackgroundThe accurate acquisition and correlation coincidence of positron annihilation signal form the basis of the lifetime spectrum sensitive characterization of microscopic defects in materials. The complex radiation background interferes with the acquisition of positron annihilation signals, pa...
