Abstract
Thermal shocks which occur during instable plasma conditions (so-called disruptions) has been simulated in electron beam and plasma accelerator tests. The resulting surface modifications and material erosion on different ceramics (pure, doped, fiber reinforced, coatings) were quantified by characterization methods such as profilometry, ceramography, and scanning electron microscopy. The measured erosion depth depends significantly on the type of ceramic material; in general it decreases with increasing thermal conductivity. Severe damage was observed in highly anisotropic material; fiber reinforced specimens show a high resistance against crack formation.
