Local electron thermal conductivity in the Tuman-2A tokamak with a rapidly varying toroidal magnetic field
Kalmykov S. G. , Lashkul S. I. , Petrov Yu. V. , Shprits I. D.
In a discharge with magnetic compression the electron thermal conductivity starts out at the anomalously high value characteristic of a tokamak. In the course of the decompression the electron thermal conductivity decreases, approaching the neoclassical value. A possible reason for this behavior is discussed. The mathematical analysis of the experimental results is described briefly.
