Outline of Final Research Achievements |
Negative hydrogen ion has one more electron than hydrogen atom. Neutral beam injector which is one of the powerful heating devices for fusion reactor include a negative hydrogen ion source which generates negative hydrogen ion beam. To enhance the NBI performance, one of the important parts is improvement of the negative hydrogen ion source performance. Basic study contributed to it needs many physical values including negative hydrogen ion temperature. In this research, diagnostics of the negative hydrogen ion temperature by using an optical cavity was successfully developed by applying an existing negative hydrogen ion density measurement. As a result, a developed instrument can measure negative hydrogen ion density and temperature, simultaneously.
