Abstract

The retention of 100 eV deuterium and tritium ions in POCO AXF-5Q graphite has been measured for the temperature range 323–1773 K. Both nuclear reaction analysis and dissolution counting were used. Below 1000 K, the retention is thought to be characterized by saturation of the near-surface region and by surface diffusion on internal porosity. Above 1000 K, the retention appears to be controlled by transgranular diffusion with decoration of high energy traps.
