| Research Abstract |
To investigate the physics of pellet plasmoid dynamics for the establishment of solid hydrogen pellet refuelling towards a nuclear fusion reactor, internal distribution measurements in the plasmoid by high-speed imaging spectroscopy have been successfully developed. In this spectroscopic system, a fiber scope with five-arms is used. The time dependence of electron density distribution in the plasmoid is investigated. The electron density in the plasmoid is compared at different background plasmas. The observations by the internal measurements contribute to the understanding of pellet ablation mechanism.
