Talk summary:

The talk about Radiation test on optical materials, will give a general introduction on testing optical materials for use in radiation environments.

A special emphasis is given to thin optical coatings, optical fibers, and fiber Bragg gratings. Here the test procedures are much more challenging than for bulk materials.

The challenges are, amongst others, conflicting standards, often online tests and the necessity to use several different radiation sources.

The talk will give an overview of test standards, especially concerning optical fibers, and a discussion of the influence of parameters such as dose rate, temperature etc.

Speaker:

Stefan Höffgen studied physics at the University of Bonn and at the UBC in Vancouver. His PhD thesis in Bonn was done in Hadron physics at the ELSA accelerator in Bonn. In 2005 he joined Fraunhofer INT as a researcher in the radiation effects group. Since then he did numerous investigations of the radiation sensitivity of all kind of electronic and optical technologies. He authored or co-authored over a dozen peer reviewed radiation effects related paper including a recent review paper on fiber Bragg gratings. He is member of the IEEE.
