| Outline of Final Research Achievements |
This work is based on a study of a nuclear fusion power generation expected as a next energy generation source using hydrogen gas. The nuclear fusion plasma has some problems. One of them is a injection method of hydrogen gas into the fusion plasma. This is owing to a low-density plasma. The objectivity of this work is to develop the high-density plasma production using hydrogen gas. It is found that the high-density plasma is attained for a higher pressure of 30 Pa, whereas for a lower pressure of a few Pa it is difficult to produce it. It is indicated that the numerical simulation of PIC-MCC method can reappear the experiments.Their results can contribute to realize the nuclear fusion.
