Atomic oxygen environment

Durability test of space-use materials in space environments

Atomic oxygen chamber

<Atomic oxygen chamber>

This vacuum chamber is used to simulate the atomic oxygen environment in LEO. The energetic atomic oxygen flow at about 8km/s is achieved by means of shooting a pulsed laser beam to the oxygen molecular oxygen gas ejected into the nozzle. We study atomic oxygen material deterioration using this chamber.
