Description

Direct measurement of divertor heat flux is an important task. But heat flux calibration is often difficult since heat diffusion in sensors is slower process than discharge duration time of present experiments. In this paper, using unsteady heat conduction model, heat flux in Heliotron J edge plasma is firstly measured. Obtained heat flux value, although it is time averaged, does not contradict edge plasma parameters. (author)
