Colorimetric diagnostics for in-situ determination of erosion and deposition rates in TEXTOR
Sputter erosion at graphite wall components is likely to prove a serious problem in future fusion devices. In present machines, eroded carbon is redeposited with hydrogen at other places on the wall surface in transparent form (a-C:H). The deposits are easy to observe because of the appearance of interference colours which mainly depend on thickness, and therefore enable direct measurements of carbon erosion.
