Division 7

Highest accuracy and reliability of the realisation, maintenance and dissemination of units of radiation physics and thermodynamics, especially of the quantities spectral power of electromagnetic radiation, temperature, heat, pressure in vacuum. Development of new methods and techniques even in extreme areas, Advisory service and development of measuring systems for new metrological challenges


Dr. Jan Wernecke was recognised for his doctorial dissertation “When Size Does Matter: Dimensional Metrology of Nanostructured Layers and Surfaces Using X-Rays” at the Technische Universität Berlin with the 2016 Ernst Eckhard Koch Prize of the Association of Friends of Helmholtz-Zentrum Berlin. His doctoral studies were carried out in the X-ray Radiometry group at the electron storage ring...

In order to become independent of the embodied standard of the international prototype of the kilogram which is kept in Paris, the SI unit of the kilogram is to be redefined by the determination of a numerical value of Planck's constant. For this purpose, the number of silicon atoms in a monocrystalline silicon sphere (weight: one kilogram) is determined at PTB within the scope of the Avogadro...

One focus of the technical work in the EUV Radiometry Working Group is the metrological support rendered to the German and European supply industry for semiconductor manufacturing in the development of EUV lithography in a great number of cooperation agreements. In 1998, the cooperation with Carl Zeiss SMT GmbH set the starting point for this field of work and has, since then, formed the basis for...
