摘要：

An air plasma diagnostic is done by Laser Induced Fluorescence (LIF) on the MESOX simulation test bench used to reproduce atmospheric reentry conditions. The parameters taken into account are the total air pressure (100 to 5000 Pa), the air flow rate (1.11 10(-6) and 5.83 10(-6) m(3).s(-1)), the microwave power (300 and 600 W) and the distance from the discharge (5 and 15 cm). The results are an increase of the atomic oxygen concentration with pressure, and a decrease with the flow rate and the distance from the discharge.
