| 概要 | C deposition characteristics on W nano-structure by two different deposition methods are investigated to study C deposition mechanisms on W nano-structure and its characteristics. The two methods were as follows: irradiation by mixed D and C ion beam, and deposition by magnetron sputtering. Differences on deposition condition such as deposition temperature, incident species and energy affected properties of C deposits. Structure of C deposits was investigated by SEM and Raman spectroscopy. D retention properties were investigated by thermal desorption spectroscopy.
It was found that C deposits on nano-structured surface have low internal stress and porous structure compared with C deposits on flat surfaces. Increase of CD4 release from C deposition layers on nanostructured surface was investigated by TDS. These results showed the effects of nano-structure on structure and thermal desorption properties of C deposits. (C) 2013 Elsevier B.V. All rights reserved. |
