Topic: Advancements in fused silica step-index fibers: a comparative study of STU-D and STU preforms in attenuation and radiation resistance
Presenter: Andreas Langner
The STU-D preform (an evolution of the STU preform) for fused silica step-index fibers has significantly lowered background attenuation while retaining good gamma radiation resistance. In this presentation to the paper we compare both types regarding attenuation and gamma radiation resistance.
