Effects of γ and neutron irradiation on the optical absorption of pure silica core single-mode optical fibres from Nufern

A measurement of the optical absorption, induced by photon irradiation up to a dose of 0.9 MGy, in Nufern silica core single-mode optical fibres is presented. In addition, the fibres were irradiated with neutrons, up to a total fluence of 2×10 14 cm −2 and the induced optical absorption was evaluate...

Description
Summary:A measurement of the optical absorption, induced by photon irradiation up to a dose of 0.9 MGy, in Nufern silica core single-mode optical fibres is presented. In addition, the fibres were irradiated with neutrons, up to a total fluence of 2×10 14 cm −2 and the induced optical absorption was evaluated for four different wavelengths: 630, 670, 681 and 785 nm.
