Abstract
Results from disruption simulation experiments are described in which specimens were exposed to 3.8 MJ m −2 energy deposition during about 10 ms from a hydrogen plasma with a density of 3×10 20 m −3 and a temperature of about 10 eV. The materials tested were pure graphite, graphite with 3 to 30% boron addition, B 4 C coat mix material, and plasma sprayed B 4 C coatings on graphite. The interaction of the thermally eroded material was measured by emission spectroscopy. The results show that the addition of boron to graphite does not significantly change the thermal erosion behaviour, or the formation of a vapour cloud in front of the specimen surface. B 4 C coat mix material melted and the eroded species show a much weaker interaction with the incident plasma than the graphite materials.
