  1. Product introduction:

  ATOMS Atomic Oxygen Exposure Measurement System is a material measurement system that simulates low earth orbit conditions, that is, a measurement system that exposes materials to hot atomic oxygen and VUV-UV light. Atomic oxygen is produced by radio frequency separation of oxygen upstream of the exposure chamber. The concentration of atomic oxygen can reach 10^15 atoms/cm through the RFX-500 high-power atomic oxygen generator. This is equivalent to about 2*10^16cm2/s atoms The oxygen flux is equivalent to the 5eV atomic flux measured with the Kapton dosimeter. It is mainly used on the ground to evaluate the changes in material properties caused by the erosion of atomic oxygen and vacuum ultraviolet when aerospace materials are exposed to low earth orbit conditions.

  The atomic oxygen density distribution on the material can be measured in situ with an atomic oxygen density profiler based on resonance absorption technology. A beam of 130.2nm atomic oxygen resonance peak directly passes through the exposure chamber, and the beam is exposed to the oxygen atoms in the chamber Absorption, the amount of absorption can be measured by the VUV solar-blind vacuum ultraviolet detector, and the atomic oxygen density distribution on the material can be determined by scanning the optical path.

  The system can also simulate the solar spectrum through UV and VUV ultraviolet light sources to evaluate the changes in material performance when the material is exposed to ultraviolet light and atomic oxygen at the same time. The interface of ultraviolet or vacuum ultraviolet light source and atomic oxygen density profiler has strong applicability and can be easily applied to the existing atomic oxygen exposure evaluation system.

  2. Product model:

  We also provide three complete atomic oxygen exposure evaluation systems to suit different applications and budgets.

  • High-profile version of the Atomic Oxygen Exposure Evaluation System

  • Standard Edition of Atomic Oxygen Exposure Evaluation System

  • Atomic oxygen exposure assessment system budget saving version

  The high version and standard version both include atomic oxygen exposure/VUV radiation and atomic oxygen density measurement system.
