Radiometry with Synchrotron Radiation

Department 7.1


Application of synchrotron radiation in the THz, IR, UV, EUV, VUV, and soft X-ray spectral range at the electron storage rings Metrology Light Source (MLS) and BESSY II for basic and applied metrological tasks:


Fourier transform infrared (FTIR) spectroscopy is a powerful technique in analytical chemistry. Typically, spatially distributed spectra of the substance of interest are registered simultaneously using FTIR spectrometers equipped with array detectors. Scanning methods such as near-field FTIR spectroscopy are a promising alternative providing higher...

A nanospectroscopic device platform has been developed for the thermoelectric detection of molecular fingerprints of soft materials at nanometer scale spatial resolution. The technique makes use of a locally generated thermal gradient converted into a thermoelectric voltage that is read out in the underlying device. The thermal gradient is generated by an illuminated atomic force microscope tip...

The metrological support of the German and European industries in the development of EUV lithography for semiconductor manufacturing is a major activity of PTB at its Berlin-Adlershof site. The close cooperation with ZEISS since 1998 forms a significant basis for the continuous development of PTB's metrological capabilities in the extreme ultraviolet spectral range (EUV). Based on the use of...
