#Nondestructive positron beams probe damage, support safety advances in radiation environments
“#Nondestructive positron beams probe damage, support safety advances in radiation environments” A combination of positron annihilation spectroscopy and transmission electron microscopy reveals new insights into how damage is formed in irradiated materials, suggesting a mechanism in which large holes in the material absorb atoms in interstitial positions in the lattice and shrink, but leave behind…
