Behavior of developed radiation-resistant silica-core optical fibers under fission reactor irradiation

摘要

Oxyhydrate (OH) doped and fluorine (F) doped fused-silica core optical fibers were irradiated in a fission reactor at 370-380 K with a fast neutron flux of about 5 x 10~16n/m~2s and a gamma-ray dose rate of about 500 Gy/s for about 24 days. Oxyhydrate and fluorine dopings improved radiation resistance of optical fibers especially in the visible range.
