Abstract

Radiation resistance of optical materials against synchrotron radiation is important, if optical components for the high energetic regime have to be produced. In the framework of the European project EUPELE, which deals with the development of optical coatings for the free electron laser at ELETTRA (Trieste), a set of CaF2substrates was irradiated with synchrotron radiation. The synchrotron radiation was varied by wavelength, dose, and high energetic background illumination. Before and after irradiation, the CaF2substrates were investigated spectrophotometrically in the VUV, VIS and IR range. The surface topology was characterised by Nomarski microscope methods. Structure investigations were carried out with X-ray diffraction measurements. CaF2shows different types of degradation like colour centre formation, surface modification, and increased VUV absorption bands. Defect formation will be presented in dependence of synchrotron irradiation conditions.
