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.


In vielen Bereichen der Industrie, v. a. der Halbleiterindustrie, werden zur Prozesskontrolle Vakuum- und Partialdruckmessgeräte eingesetzt. Für die in-situ Kalibrierung und zur Überwachung im Hoch- und Ultrahochvakuumbereich kommen Ionisationsvakuummeter zum Einsatz. Bei ihnen werden mithilfe schneller Elektronen Gasmoleküle ionisiert und der resultierende...

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...

Am Markt verfügbare Halbleitersensoren weisen nur eine sehr begrenzte Ultraviolett (UV)-Empfindlichkeit auf. Selbst die besten konventionellen UV-Photodioden haben eine Quantenausbeute von unter 80 % im Spektralbereich zwischen 200 nm und 300 nm. Hierbei wird stets die externe...

Annual Report 2020

The 2020 pandemic year also posed several challenges for Division 7 and in particular for the new management team established last year. But these were overcome through a high level of responsibility and commitment at all levels. In the field of international cooperation, it was even possible to support a number of developing ...
