Radiation-hardness studies of high OH**- content quartz fibres irradiated with 500 MeV electrons

We investigated the darkening of nine high OH**- fibre types irradiated with 500 MeV electrons from the Linac Injector of LEP (LIL) at CERN. The transmission of Xe light was measured in situ in the 350-800 nm range. The induced attenuation at 450 nm is typically 1.52 plus or minus 0.15 dB/m for a 10...

Sumario:We investigated the darkening of nine high OH**- fibre types irradiated with 500 MeV electrons from the Linac Injector of LEP (LIL) at CERN. The transmission of Xe light was measured in situ in the 350-800 nm range. The induced attenuation at 450 nm is typically 1.52 plus or minus 0.15 dB/m for a 100 Mrad absorbed dose. Two- parameter fits for darkening and recovery are presented. After irradiation the tensile strength remains essentially unchanged. For Polymicro quartz core fibres the tensile strength is typically 4.6 plus or minus 0.4 GPa.
