Additional equipment

With the unique characteristics of the infrared synchrotron radiation source from the mid to the far infrared and THz spectral range, new and exciting experiments in material and life sciences are now possible.

The end-stations at IRIS can be used for spectroscopic investigations of biological systems (cells, tissues, fibres), for microscopy of same and for the investigations on the structural and functional interactions of proteins. In addition, vibrational, structural and electronic properties of liquids, solids, surfaces and thin layers can be studied. This allows to address scientific problems in the fields cultural heritages and noval materials. For example, the high brilliance in the THz spectral range is used to study the optical conductivity at low temperatures of small-sized and unique single crystalline samples of novel materials, e.g. high-Tc superconductors.
