Description
Optical fibres experience significant differences in Radiation induced absorption (RIA) depending upon the temperature environment. At the LHC upgrade there are plans in some cases to mount optical fibres on or near to cold surfaces at sub-zero temperatures. Consequently a programme of characterization of optical fibre's RIA in cold environments is essential for identification of acceptable components and qualification of the final data links.
We report temperature dependent radiation induced absorption from cold tests of optical fibres which are candidates for a future high energy physics detector. The optical fibre was exposed to ionizing radiation at -20 deg. C.
