Abstract:

The electron heat transport is studied by analysis of observed cold pulse propagation during gas modulation in HL-2A ohmic discharge. The electron heat transport is analyzed using perturbation transport equation. According to the results of curve fitting and numerical calculation with the electron temperature perturbation measured from modulated gas puffing experiment during ohmic discharge on HL-2A tokamak, the character of the electron heat transport coefficient profile at high field side is χ = 15 -14 (1 -r ²)²m² ·s^-1 .

Key words: Electron heat transport , Density modulation , Cold pulse propagation
