Abstract

Highlights: [•] The carbon-dominant mixed-material layer was formed on the tungsten surface after 15th plasma exposure in LHD. [•] The largest enhancement of deuterium retention was found to be about 21. [•] The major deuterium desorption temperature was shifted toward higher temperature side. [Copyright &y& Elsevier]
