Abstract

Tungsten (W) targets have been exposed to high density (n(e) = 2 eV. The maximum film thickness was similar to 2.1 mu m after a plasma exposure time of 120 S. He-3 nuclear reaction (NRA) analysis and thermal desorption spectroscopy (TDS) determine that the presence of a thin carbon film dominates the hydrogenic retention properties of the W substrate. Thermal desorption spectroscopy analysis shows retention increasing roughly linearly with incident plasma fluence. NRA measures a C/D ratio of similar to 0.002 in these films deposited at high surface temperatures. (C) 2009 Elsevier B.V. All rights reserved.
