Sputtering of plasma facing material by simultaneous bombardment with carbon and deuterium ionsFunded under: EAEC-FUSION 12C
The sputtering of material exposed to a plasma with an electron temperature of 40 eV containing deuterium ions and carbon ions has been investigated using the computer program TRIDYN. The sputtering yields for the various elements were calculated dependent on the plasma ion fluence and the carbon concentration in the plasma. The question, whether erosion of the target material or deposition of the carbon atoms occurs, strongly depends on the carbon concentration in the plasma and the target species. A transition from an erosion phase to a deposition phase during the exposure was observed under certain conditions.
