Radiometry with Synchrotron Radiation

Department 7.1

Tasks

Initiates file download Application of synchrotron radiation in the UV, EUV, VUV, and X-ray spectral range at the electron storage rings Metrology Light Source (MLS) and BESSY II for basic and applied metrological tasks with main focus on radiometry:

Operation and application of MLS and BESSY II as primary source standards of calculable synchrotron radiation
Realisation of spectral responsivity scales in the UV, VUV, EUV, and X-ray ranges by means of cryogenic radiometers as primary detector standards
Calibration of radiation sources and detectors from the UV to X-rays
Photon diagnostics and materials research at X-ray lasers
Characterisation of space instrumentation
Reflectometry on optical components and materials from the UV to X-rays, in particular for EUV lithography
Investigation of nanolayers and nanoparticles applying scattering techniques and X-ray reflectometry
Quantitative characterization of surfaces and thin layers applying VUV ellipsometry and electron spectroscopy

Die zunehmende Komplexität von nano-strukturierten Oberflächen bei technologischen Anwendungen ist eine enorme Herausforderung auch für deren metrologische Charakterisierung. Besonders in der Halbleiterindustrie sind hochkomplexe und mehrdimensionale Nanostrukturen, die aus unterschiedlichen Materialien zusammengesetzt sind, von großer Bedeutung. Im PTB-Laboratorium am Elektronenspeicherring BESSY...

PTB and ASML are putting a new test beamline into operation at BESSY

Increasing miniaturization in the microelectronic sector has created inevitable facts: In the future, structures on microchips and on other components will have to be manufactured by means of lithography in the EUV range, which means using extremely short wavelengths of just 13.5 nm. For test measurements, the...

Fundamental material parameters such as the interaction cross sections used to describe the interaction of matter with radiation are very important, both for fundamental research and for diagnostic and analytical applications. In collaboration with Fraunhofer IPM in Freiburg im Breisgau, interaction cross sections for the photoionization of noble gases in the VUV spectral range have recently been...
