Temperature and Synchrotron Radiation

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


The DFG – project "Bayesian compressed sensing for nanoscale chemical mapping in the mid-infrared regime" has started at the beginning of this year. The project aims at the reduction of large amounts of data and measurement times in scanning probe-based spectroscopy with broadband infrared synchrotron radiation. Scanning probe techniques with their pixel-by-pixel data acquisition and conventional...

Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have implemented a novel pressure measurement method, quasi as a byproduct of the work on the "new" kelvin. In addition to being new, this procedure is a primary method, i.e. it only depends on natural constants. As an independent method, it can be used to check the most accurate pressure gauges, for which PTB is known as the world...
