Comparative study of magnetic reconnection rates in ASDEX Upgrade and EAST tokamaks
Magnetic reconnection during a sawtooth crash in a tokamak can be characterized by the radial velocity of the hot core. This paper presents a comparative study of reconnection rates observed in ASDEX Upgrade and EAST tokamaks. The findings demonstrate qualitative agreement with theoretical predictions, indicating that two-fluid effects, such as parallel electron pressure gradient and electron inertia, are required to explain the experimental results. Based on data from the ASDEX Upgrade and EAST experiments, as well as simulation results, the reconnection rate for ITER is estimated.
