| Outline of Final Research Achievements |
The purpose of this project is to clarify the physical mechanism of the nonlinearity and nonlocality of the heat pulse propagation in magnetically confined plasmas. Here, we performed (1) development of the helium beam emission spectroscopy system in a linear magnetized plasma and (2) data analysis of the heat pulse propagation experiment in large fusion devices. Within the project, we achieved (1) setup of the helium supersonic molecular beam injection system for the helium beam emission spectroscopy system, (2) exemplifying of the nonlinearity and nonlocality of the heat pulse propagation and (3) proposing of an analysis method for reconstructing the data of the Thomson scattering system with a high time resolution.
