A device to characterize optical fibres

A device to characterize optical fibres

ATLAS is a general purpose experiment approved for the LHC collider at CERN. An important component of the detector is the central hadronic calorimeter; for its construction more than 600,000 Wave Length Shifting (WLS) fibres (corresponding to a total length of 1,120 Km) have been used. We have built and put into operation a dedicated instrument for the measurement of light yield and attenuatio...

A bottleneck for optical fibres.

authors stimulated Cos cells with epidermal growth factor, they first detected activated Ras at the nearby plasma membrane. Active Ras then rapidly spread into the body of the cell, probably reflecting the internalization of a signalling complex composed of Ras, a guanine-nucleotide-exchange factor and perhaps the receptor. In PC12 cells that were induced to differentiate with nerve growth fact...

Radiation damage to polymer optical fibres

Recently, polymer optical fibre dosimeters have been proposed for use in radiation oncology. Prior to clinical acceptance the effects of radiation on the materials involved must be assessed. In this work, the effects of radiation on mechanical strength and power transmission of polymer optical fibres were investigated. The fibres were subject to high energy electrons and photons generated by a ...

Tailored optical fibres

The paper defines the field of special optical fibers. Classification of tailored optical fibers was introduced. The characteristics of main families of such fibers were presented. There were discussed the following fibers: isotropic made of soft glass, of complex refraction – including ring-index, polarization maintaining and polarizing, elliptical, holey with macro holes and porous, nonlinear...
