Outline of Final Research Achievements

Reactive species generated in atmospheric-pressure discharges, including lightning discharges, are expected to be applied in a wide-ranging technology fields, such as the environment, energy, medicine, and agriculture. However, there are still many unresolved issues in their generation mechanisms. One of the reasons for this is that the behavior of the atmospheric-pressure discharges is extremely complex. This complexity imposes remarkable challenges in the measurement of the electron density, electric field, and reactive species. In order to overcome the difficulty, we developed diagnostic technologies that can measure the electron density, electric field, and reactive species in the lightning discharges.

Academic Significance and Societal Importance of the Research Achievements

大気圧放電の内部では、反応性に富んだ活性種が効率よく生成される。活性種の応用技術は、燃焼技術や環境汚染物質の浄化技術、特定疾患の選択的治療技術などに代表されるよう多岐にわたるが、適用が遅滞している事例も数多く存在する。これは、活性種の生成機構に未解明な部分が数多存在することが一因として挙げられる。本研究で開発したセンサ群を駆使することで、活性種の生成機構解明や活性種応用技術の最適化・新規適用を達成することが可能となる。
