25 years of BESSY II light source for the good of society

Helmholtz-Zentrum Berlin (HZB) is celebrating the 25 years of existence of BESSY II together with the international scientific community. More about the highlights from 25 years of research at BESSY II, the plans for the future, and the people who reliably operate the machine are to be found in the special anniversary magazine here.

When BESSY II in Berlin Adlershof went into operation in September 1998, it was a milestone for the reunified Berlin and in some ways a starting point for the success story of Adlershof. After only four years’ construction time, the successor to the first Berliner synchrotron radiation source that was previously in West Berlin (BESSY I) now stood in the eastern part of the city.

Today, BESSY II is a magnet for scientific exchange. Every year, the research facility receives more than 2700 visits from guest researchers from all over the world, who use the special X-ray light for their research. BESSY II has delivered results that have led to breakthroughs in many research fields. Helmholtz-Zentrum Berlin (HZB) is therefore celebrating the 25 years of existence of BESSY II together with the international scientific community. More about the highlights from 25 years of research at BESSY II, the plans for the future, and the people who reliably operate the machine are to be found in the special anniversary magazine here.

BESSY II is a material discovery machine

The most important experiments today are those for developing the materials we need for an environmentally friendly energy supply of the future.

Be it solar cells, catalysts for green hydrogen, batteries, or quantum materials – the special X-ray light (aka synchrotron light) from BESSY II can be used to look inside everything. HZB and its partners have expanded these experimental possibilities considerably in the recent years. In-situ and in-operando measurements allow researchers to “watch live” how a battery gets charged or discharged, for example, or how a catalyst works. That helps experts to further optimise the materials they are made of so that they work even more efficiently.

Plans for the future

25 years of BESSY II are incentive for Helmholtz-Zentrum Berlin to continue operating the light source at the highest level, and to allow societally important research to continue into the future. Accordingly, the work for a comprehensive upgrade to BESSY II+ has been underway in the recent months. Many components of the accelerator and several experimental stations (beamlines) are being renovated and modified in order to offer even more attractive research possibilities for science and industry. HZB experts have also developed a concept for a successor source in Berlin Adlershof, which will allow this important research to continue further still for decades to come. After all, a powerful light source that delivers soft X-ray light is essential for Germany as a science and technology location, and secures jobs in the long term.
