Welcome to the HZB User Facilities

The Helmholtz-Zentrum Berlin für Materialien und Energie HZB operates two large scale research facilities: the upgraded medium flux research reactor BER II on Lise-Meitner-Campus in Berlin-Wannsee and the third generation synchrotron source BESSY II 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.


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.
