Study for Ground Accelerated Test of Space Radiation Effect

Under the space charged particle radiation, the damage and failure is the important content in the investigation of space material science, and ground accelerated test is the important study method and technology for radiation damage on materials. In the paper, the methods and related concepts in ground accelerated test are introduced, and the optical quartz glass is set as an example to demonstrate radiation accelerated test and simulation equivalent range. The studies about ground accelerated test will help to provide the scientific criteria for materials behavior, spacecraft design and materials selection under space charged particle radiation.
