We had conducted helicon plasma irradiation test onto tangsten/cupper composite target, which was the candidate for the divertor plate. At that time, temperature evolution measured by IR camera and thermocouples could not be well explained. By using recently developed heat conduction model for long time heat flux sensor, it is confirmed that temperature distribution in the target and irradiation surface temperature can be explained. In this work, this irradiation test is reconsidered.
