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


In cooperation with the Helmholtz-Center, Berlin, and the Tsinghua University, Beijing, a so-called proof of principle experiment towards Steady State Micro Bunching (SSMB) was successfully performed at the Metrology Light Source (MLS), the electron storage ring of PTB in Berlin-Adlershof. It could be proven that approximately one µm long structures created within a stored electron bunch of a few...

The announcement made by the large semiconductor manufacturers Samsung and TSMC in autumn 2018 that they are going to use EUV lithography for the manufacturing of high-end processors marks the commercial breakthrough of this technology after a long development phase. PTB has contributed to this development in metrological matters through its work at the synchrotron radiation sources BESSY II and...
