Abstract

We had performed the fundamental experiments to investigate the characteristic of the plasma expansion due to ion species configuring the plasma by using a linear device. Our results confirmed that the plasma expands due to magnetic field divergence and the peak value of the ion flux contributing to the plasma heat load decreases with magnetic field divergence even if the ion configuring the plasma changes to different species or mixes.

Keywords

divergent magnetic field, divertor, heat load, linear plasma device, mixed plasma, plasma-wetted area
