Post-mortem analyses of gap facing surfaces of tungsten tiles of T-10 ring limiter

Atomic spectrometry update: review of advances in the analysis of metals, chemicals and materials

“…A study by Pisarev et al measured tungsten tile surfaces after decommissioning using several techniques (LIBS, SEM/EDA, XRD, TDS and NRA). 172 A deposited film was measured in 5 mm and 1 mm gaps to their full depths of 22 mm and 15 mm, respectively. The films were mainly formed from the Li limiter and C from sputtered volatile hydrocarbons from the Tokamak walls.…”
