abstract = "The processes of defect formation and evolution in ultrapure glass under 1 MeV electron irradiation were investigated by the measurement of electron paramagnetic resonance (EPR) spectra and optical absorbance. The results show that the 1 MeV electron irradiation of the ultrapure glass can induce the formation of E{\textquoteright}γ centers, and the structure of the E{\textquoteright}γ center transform from E{\textquoteright}γ(1) center to E{\textquoteright}γ(2) center with the increasing irradiation fluence, and this variation also affects the defect optical absorption property in the material. During the room temperature aging process, the defects anneal process induces the recovery of the optical property of the ultrapure glass. It is worth to note that the defect structure varied during the ageing process, namely, the E{\textquoteright}γ(2) center transform to E{\textquoteright}γ(1) center, and the variation of the defect structure induced the no synchronous property between the defect anneal and the optical absorption recovery.",
