摘要：The fiber form nanostructure of tungsten surface called "fuzz", which degrades the performance of tungsten material, has been observed on linear devices, tokamak and stellarator. We developed a three-dimensional (3D) kinetic Monte Carlo (KMC) code SURO-FUZZ to investigate the formation of fuzzy nanostructure in the micro- and second-scales. The time evolution of fuzz morphology under helium bombardment is studied by SURO-FUZZ. The growth rate of tungsten fuzz shows a good agreement with the experimental results.
