| 英文摘要 | LED-fiber system has been used to monitor BLM and BESIII EMC. A radiation hard silica optical fiber is essential for its stability and reliability. Three types of silica optical fibers, silicone-clad silica optical fiber with high OH- content (SeCS), silica-clad silica optical fiber with low OH- content (SCSL) and silica-clad silica opical fiber with high OH- content (SCSH) were studied. In the experiment, 12 groups of fiber samples were irradiated by Co-60 and 3 groups of fiber samples were irradiated by BEPCII background radiation. Radiation hardness: the radiation hardness of SCSH is best and meets the radiation hardness requirement for LED-fiber monitor of BLM and BESIII EMC. The transmission of SeCS and SCSH decreased to around 80% under the Co-60-irradiation of 5 Gy and 10 Gy, respectively. The radiation hardness of SeCS is worst because of its silicone cladding. Recovery characteristics: Co-60-irradiated by the same doses, there were both more annealable and more permanent color centers formed in SeCS than SCSI, and for the same kind of fibers, as long as the irradiated doses are under a certain amount (for example, less than 5 Gy for SeCS), the higher the doses, both the more annealable and the more permanent color centers are formed.
