Abstract The change in optical transmittance of JGS3 optical quartz glass was studied using ground simulation for the space environment conditions of high vacuum, heat sink, and 140 keV low energy protons and the kinetic model for the evolution of color centers in the process of radiation damage was explored. The experimental results show that radiation damage occurs in the surface layer of quartz glass under large flux and low-energy proton radiation. The optical density change increases rapidly and then a saturation trend appears with increasing absorption dose. A kinetic model for the evolution of color centers in quartz glass irradiated with protons is proposed based on experimental data, from which the change in optical density can be given. The model fitted curve is similar to experimental ones. It is believed that the proposed kinetic model can be used in the quantitative description for the change in optical property of quartz glass with increasing absorption dose under proton radiation with low energy.
