Welcome to the HZB User Facilities

The Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) operates the large scale research facility BESSY II a third generation synchrotron source on Wilhelm-Conrad-Röntgen-Campus in Berlin-Adlershof. In addition, it is home to a number of state-of-the-art on-site laboratories and HZB CoreLabs. All these research facilities are designed to serve researchers from universities, foreign research institutions and industry.

After 46 years of successful research with neutrons, the operation of the Berlin research reactor BER II - located at the Lise-Meitner-Campus in Berlin-Wannsee - ended on December, 11 2019. If you have any question concerning the BER II user support please contact the former BER II User Office Neutrons in Berlin-Wannsee.

User Facility BESSY II in Berlin-Adlershof


BESSY II provides ultrabright photon beams from the long wavelength Terahertz region to hard X-rays with complete control of the polarization of the radiation and energy range. The combination of brightness and time resolution makes BESSY II the ultimate microscope for time and space, since both femtosecond time and picometer spatial resolutions are available.
