Temperature and Synchrotron Radiation

Division 7

Warm or cold, light or dark: thermodynamic and radiation physics issues are the focus of Division 7.

Tasks

The main tasks of the approximately 100 employees of Division 7 on the Berlin-Charlottenburg campus are thermometry, thermal energy, cryosensorics, optical radiometry and vacuum metrology.

Metrology with synchrotron radiation, on the other hand, is the field of activity of the approximately 75 employees of Division 7 at the Berlin-Adlershof site with the synchrotron radiation sources BESSY II and Metrology Light Source (MLS).

With its research and development work, Division 7 is involved in the European Partnership on Metrology (EPM), in the future metrological topics of digitization, energy, quantum technology, systems metrology, environment and climate, as well as in the field of nanometrology.

Extracellular vesicles (EVs) are nanometer-sized cell-derived particles in body fluids and can be used as potential biomarkers for diseases such as cancer, inflammation and cardiovascular disease. EVs gained a lot of interest as they are released from all cell types and their biochemical composition, concentration and function are disease-dependent...

Until now, it has not been possible to measure the radiated power of millimeter waves in the terahertz spectral range in the so-called H-band with frequencies from 220 GHz to 330 GHz traceable to the International System of Units. The solution to this problem is a new type of terahertz detector, which was developed as part of a Franco-German cooperation project.

The optical constants fully describe how a material transmits, reflects, absorbs, refracts or scatters light. Their precise knowledge is therefore of central importance for optical technology. As part of the European joint projects "Advanced Traceable Metrology for Optical Constants" (ATMOC) and "14 Angstrom CMOS IC technology" (14ACMOS), PTB has started to build up a database of optical constants...
