Temperature and Synchrotron Radiation

Division 7

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


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 70 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 Metrology Programme for Innovation and Research (EMPIR), in the future metrological topics of quantum technology, environment and climate, energy, digitization and medicine as well as in the field of nanometrology.


A joint research proposal between the SENTECH Instruments GmbH, the Technische Universität Berlin, the Helmholtz-Zentrum für Materialien und Energie Berlin GmbH and the PTB has been approved for the ProFIT program of the Investitionsbank Berlin IBB (program for boost of research, innovation and technology).

Annual Report 2021

The year 2021 was difficult for Division 7 not only because of the pandemic, but also due to departures and staff absences due to illness. Nevertheless, it was very successful due to a strong commitment and good cooperation at all levels. A number of new colleagues were recruited, third-party funding remained stable at a very high level, publications, doctorates and also calibration revenues...
