Wright}, title = {Helium effects on tungsten surface morphology and deuterium retention}, abstract = {Recent experimental results on tungsten surface morphology, especially nano-structure (fuzz), induced by helium plasma exposure at temperatures between 1000 K and 2000 K are reviewed. This structure was firstly reported in 2006. In this review, most of experimental results reported so far including characteristics and formation conditions of the nano-structure in both linear plasma devices and magnetic confinement devices, erosion and arcing by steady-state plasma exposure and ELM-like pulsed heat or pulsed plasma exposure by a laser and a plasma gun are summarized. In addition, He effects on D retention under simultaneous D/He irradiation on tungsten are presented.}, year = {2013}, journal = {Journal of Nuclear Materials}, volume = {442, Supplement}, number = {1–3, Supplement 1}, pages = {S267 - S272}, url = {http://www.sciencedirect.com/science/article/pii/S0022311512005582}, doi = {http://dx.doi.org/10.1016/j.jnucmat.2012.10.023}, language = {eng}, }
