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


Im Rahmen einer Kooperation mit dem National Institute of Metrology (NIM, China) ist es gelungen, die Unsicherheit bei der Darstellung der SI-Basiseinheit Kelvin für Temperatur über den Tripelpunkt von Wasser in der PTB auf weniger als 20 µK zu verbessern. Darüber hinaus konnte durch direkte Vergleichsmessungen mit einer am NIM hergestellten Wasser-Tripelpunktzelle im Rahmen eines...

By means of improved measurement procedures, PTB employees from the field of spectrometry with synchrotron radiation have succeeded – in cooperation with partners from industry – in experimentally confirming the different energy dependencies of partial photoionization cross sections which could so far be predicted only by theoretical calculations. Due to this, the quantification approach of...
