| Outline of Final Research Achievements |
A laser-driven plasma wind tunnel was developed in this study as a simulator of high-speed continuous atomic oxygen flows in the low earth orbit environment. Laser diagnostics of the plume revealed the time-averaged flow velocity and translational temperature of the flows to be 6.1 km/s and 1216 K, respectively. The flux density for pure oxygen flows was estimated as 1.3 × 1025 atom/m2s. The flow velocity could be increased to 6.6 km/s by mixing oxygen with helium at a mole fraction of 0.23. An orbital velocity of 7.8 km/s could be achieved by increasing the helium mole fraction to 0.58.
