Deuterium retention in recrystallized tungsten exposed to high-flux plasma with fluences up to 1 × 1029 m−2

Deuterium retention in recrystallized tungsten exposed to high-flux plasma with fluences up to 1 × 1029 m−2

Plasma fluence at the divertor of a future magnetic confinement fusion device can accumulate up to ∼10 ^28 –10 ^29 m ^−2 per year. Yet hydrogen isotope (HI) retention under such high-fluence plasma exposure has been rarely reported. To investigate deuterium (D) retention in tungsten (W) exposed to s...
