[SIT22-P22] Development for hydrogen diffusion experiments under Ar/D2 and D2O condition
Keywords:Hydrogen, diffusion, SIMS
The diffusion annealing system in this study could chose between D2O line and Ar/D2 line for the diffusion source. In addition, this system chose flow type and close type with vacuum system for the control of partial pressure in the crystal surface. Therefore, we need to estimate the residue of H2O and D2O absorbed in the line and quarts tube when the Ar/D2 gas line are selected.
The quantitative analyses for residue of absorbed water were estimated by annealing of apatite crystals in the different condition with the depth profile by Kyoto 4f-e7 secondary ion mass spectrometry (SIMS).
This talk will discuss the results of different diffusion source in the apatite crystals and methods of control the partial pressure of Ar/D2 diffusion experiments.
