| Outline of Final Research Achievements |
Nanoscale plasma generation and measurement system has been developed based on a nanoscale metallic tip and planer discharge in liquid. It is revealed that the localized discharge can be observed on the surface of micrometer scale metallic tip where carbon nanotubes （diameter: 1 nm）are coated, indicating the nanoscale plasma generation may be realized around the nanotubes. The time evolution of initial nanoscale discharge is also systematically investigated, which reveals that the direct ionization model is found to be reasonable in the primary streamer propagation.
