Journal ArticleDOI
Modelling deuterium release during thermal desorption of D + -irradiated tungsten
M. Poon,A.A. Haasz,J.W. Davis +2 more
TL;DR: In this article, the authors used SIMS measurements of implantation profiles and using the multi-trap diffusion code TMAP7 to model the thermal desorption profiles of single crystal tungsten.
Journal ArticleDOI
Isotopic effects in hydrocarbon formation due to low-energy H+/D+ impact on graphite
B.V. Mech,A.A. Haasz,J.W. Davis +2 more
TL;DR: In this paper, mass spectrometry in the residual gas was used to measure the hydrocarbon formation rates as a function of pyrolytic graphite temperature (300-1000 K) and ion energy (10-200 eV/H or D) for mass-analysed H3+ and D2+ beams.
Journal ArticleDOI
Hydrogen and helium trapping in tungsten under single and sequential irradiations
TL;DR: In this article, the authors measured the trapping of hydrogen and helium in polycrystalline tungsten irradiated with 500 eV He +, H + and D + ions individually or sequentially.
Journal ArticleDOI
Deuterium retention in tungsten for fusion use
TL;DR: In this article, the retention of deuterium in polycrystalline W foils has been measured as a function of ion fluence and implantation temperature, and the retention enhancement is attributed to an increase in the D diffusion coefficient, which allows a greater diffusion depth.
Journal ArticleDOI
Hydrogen and helium trapping in tungsten under simultaneous irradiations
TL;DR: In this article, the authors measured hydrogen and helium trapping in polycrystalline tungsten under simultaneous He + -H + and He + −D + irradiation by thermal desorption spectroscopy.
