Abstract: The surface cooling mechanisms of nanostructured tungsten are reported in terms of a decrease in secondary electron emission and an increase in radiation emissivity. The suppression of physical sputtering of nanostructured tungsten bombarded by argon ions is demonstrated, showing a surface morphology which gives a minimum sputtering yield. Recovery of He – defected tungsten towards flat surface is shown for Powder Metallurgy Tungsten and ITER grade-W. TFGR W - 1.1%TiC/H gives a slower recovery process than PM-W.
