Besides the neutron source BER II in Berlin–Wannsee, the Helmholtz-Zentrum-Berlin (HZB) operates another large-scale research facilities called BESSY II which is located in Berlin-Adlershof. This 3rd generation storage ring generates highly brilliant synchrotron radiation from the terahertz to the UV, soft- and hard X-ray spectral region. X-ray spectroscopy, photon scattering, nanometer microscopy as well as time-resolved studies are used to investigate various kind of samples with main emphasis on materials relevant for energy, storage and information technology. Gaseous particles, liquids, thin films, surfaces, bulk solids and crystals can be explored either under steady state conditions, in-situ or in-operando. Moreover, experiments can be performed under sophisticated sample environments like extremely low temperatures, strong and directional magnetic fields, ultrahigh vacuum conditions, ambient and high pressures or strong electric fields. The recently opened CoreLab EMIL attached to the BESSY synchrotron main hall is a specialized energy material in-situ laboratory dedicated to energy and catalysis research.
The sample environmental group serves to maintain an efficient, flexible and specialised sample-environmental infrastructure and is based on following expertise:
- Cryogenics and cryostats
- Strong and spatially directed magnetic fields (static, pulsed)
- Gas pressure and ambient pressure cells
- Vacuum technology
- Electric fields
- Nanometer positioning
