Outline of Final Research Achievements

The validity of OH measurement in immediate vicinity of the dielectric surface was discussed using two geometries of laser-induced fluorescence (LIF) measurement, and surface distribution and temporal profiles of OH were examined. A comparison of parallel- and perpendicular-LIF techniques for OH measurement revealed that OH was mostly produced in a region several tens of lm above the dielectric surface.
Ground-level atomic nitrogen was observed using using two-dimensional two-photon absorption laser-induced fluorescence (TALIF) techniques under atmospheric pressure. Radial distribution of atomic nitrogen density just after discharge pulse was measured at high resolution. Ground-level atomic oxygen during the streamer propagation was measured 2D-TALIF. The atomic oxygen was produced 20-140 ns after beginning of streamer propagation. It directly indicated that atomic oxygen was mainly generated in secondary streamer.
