| Outline of Final Research Achievements |
Energy transfer processes on plasma with multi-phase matters, in which solid, liquid, vapor, and plasma phase simultaneously appear in a narrow space, have been studied using a magnetized coaxial plasma gun and a steady state/pulse combined plasma irradiation device. The absorbed energy density was measured with calorimeters having heat receiving materials of aluminum (Al) and tungsten (W). As a result, the absorbed energy on the W material was ~70% of that in the incident helium (He) pulsed plasma, whereas only ~20% of the plasma energy was absorbed on the Al material. Al layer formation was identified with a high-speed camera with a bandpass filter of 394 nm, and dynamic behaviors of Al neutral and He ion emissions were revealed using a time-resolved multichannel spectroscopy.
