摘要:
Low energy ((similar to)eV) deuterium (D) plasma-driven permeation (PDP) experiments for tungsten have been performed in the temperature range of 750-973 K. The transient permeation behavior is found to be strongly affected by trapping effect. The steady state PDP fluxes increase rapidly with increasing temperature below 910 K but increase slowly with increasing temperature above 910 K. The two different temperature dependences of PDP fluxes are due to different temperature dependences of D recombination coefficients on the front surface.
