Abstract
The first simultaneous measurements of the current, temperature, and d ensity profile changes during a disruption have now been made on the D III-D tokamak. In radiative collapse disruptions the current profile m easured using the motional Stark effect diagnostic is observed to flat ten rapidly (similar to 1.2 ms) at the final stage of a 10 ms thermal quench and just prior to the start of the current quench. The current flattening is faster than can be explained by relaxation due to classi cal or neoclassical resistive processes.
