Surface chemistry and physics of deuterium retention in lithiated graphite
Lithium wall conditioning in TFTR, CDX-U, T-11M, TJ-II and NSTX is found to yield enhanced plasma performance manifest, in part, through improved deuterium particle control. X-ray photoelectron spectroscopy (XPS) experiments examine the affect of D irradiation on lithiated graphite and show that the surface chemistry of lithiated graphite after D ion bombardment (500 eV/amu) is fundamentally di...
متن کاملTernary Recombination In Deuterium Plasma
Abstract. The recombination of D3 ions with electrons was studied in plasma over a broad range of pressures and temperatures varying from 77 K up to 300 K using flowing afterglow (FALP) apparatus. Reported is observation of dependence of overall recombination process on temperature, helium buffer gas pressure and hydrogen partial pressure. The effective plasma recombination rate is driven by bi...
متن کاملFlux dependence of carbon chemical erosion by deuterium ions
The chemical erosion of carbon in interaction with a hydrogen plasma has been studied in detail in ion beam experiments, and erosion yield values are available as a function of ion energy and surface temperature. However, the conditions in the ITER divertor cannot be simulated by ion beam experiments, especially as far as ion flux is concerned. Therefore, a joint attempt was made through the EU...
