Studies on Radiation Defects in Tungsten Induced by W Self-Implantation

Abstract:

Article Preview

Undamaged and damaged tungsten were investigated by means of positron spectroscopy and AFM surface images. Three different lifetimes (corresponding to dislocation loops, mono-vacancies, vacancy clusters and large size voids) were observed with different intensities. AFM shows the transition from hillocks to pinholes after W self-implantation.
