Metrology with Synchrotron Radiation

The Physikalisch-Technische Bundesanstalt (PTB) is the national metrology institute and the highest authority when it comes to correct and reliable measurements in Germany. Since 1982, PTB has also been using synchrotron radiation for metrological tasks. The more than 70 employees of the departments 7.1 Radiometry with Synchrotron Radiation and 7.2 X-ray Metrology with Synchrotron Radiation maintain and use for this purpose a Laboratory at the storage ring BESSY II of the Opens external link in new windowHelmholtz-Zentrum Berlin (HZB) as well as PTB's own Metrology Light Source (MLS) in Berlin-Adlershof.

The main focus of the work is on the following areas:

  •  Fundamentals of metrology, radiometry
  •  Metrology for industry, EUV lithography
  •  Research and development for optical technologies, space instruments
  •  Materials metrology, nanometrology

In scanning probe microscopy (SPM) images of surfaces are created by moving a tip across the surface. Research in SPM aims to find suitable tips and physical interaction mechanisms which uncover specific surface properties. An important and proven method for mapping the magnetic order of ferromagnetic surfaces is magnetic force microscopy based on the magnetic dipole interaction ...

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...
