“…These results confirm the observed differences between hydrocarbon deposition in gaps at ASDEX Upgrade and TEXTOR and agree very well with the observed temperature dependency of hydrocarbon deposition at remote surface [8]. This is possibly due to the observation that the sticking probability at least of CH 3 + hydrocarbons does not very significantly in the relevant surface temperature range, while the D and C are still deposited with approximate constant ratio of D/C≈0.7 and an exponential fall-off length from the gap entrance of ≈3mm [8]. This is a very encouraging result for ITER, suggesting that moderately elevated temperature can significantly reduce tritium accumulation in tile gaps.…”

“…Material samples can be inserted into the lower divertor of DIII-D and exposed to selected plasma discharges. Net material erosion and redeposition can be measured and results can be used to benchmark modeling codes [3].…”
