摘要：

Interaction of the plasma with the main chamber is observed with infrared thermography during disruption of JET plasmas. Taking into account the effect of surface layers on some of the limiter surfaces, we make the first estimates of the energy density deposited on the walls. Assuming toroidal symmetry and extrapolating over the whole JET vessel gives a good energy balance with the pre-disruption stored energy. (c) 2007 Published by Elsevier B.V.
