Dogyun HWANGBO

Nebuta Museum WA RASSE

Global Plasma Forum in Aomori, 2023.Oct.18

I am insterested in topics of plasma physics and controlled fusion: plasma-surface interactions, divertor-relevant physics, atmospheric plasma sources and its applications.

筑波大学プラズマ研究センターの「プラズマ-材料相互作用」グループを担当しています。
核融合炉における周辺プラズマと炉壁の相互作用に着目し、直線型プラズマ装置を用いた高温プラズマー金属壁の相互作用の研究を行っています。また、プラズマー材料相互作用の産業応用を目指して、大気圧プラズマ源の開発及びプラズマ計測を行っています。プラズマ照射による材料の表面・内部変化に興味がある方、歓迎します!
