Modulated Phase Lag Relations to Determine the Scaling Law of the Electron Thermal Conductivity in Tokamak

We propose a method to determine the scaling law of the electron thermal conductivity x⁰_eTe^λ_e with modulating heat pulses. Relation between temperature phase lag and parameters (x⁰_e, λ) is established, from which the electron thermal conductivity in center region of CT-6B tokamak is determined.
