BESSY II from above

Digital walk through BESSY II

How does an accelerator actually look from the inside? And how is the highly desired X-ray light produced, which researchers from all over the world use? Join us on a tour of the electron storage ring BESSY II in Adlershof, which produces the brightest light in Berlin! Link to the video


Maintenance work on BESSY II

What is happening at BESSY II right now?

The storage ring BESSY II is down for nine weeks this year while urgent maintenance is being performed and new components are being installed. There is much going on behind the scenes to ensure that BESSY II will be available as reliably as ever for our guest researchers. Find more out about our summer shutdown projects.

Achieving climate targets with building integrated photovoltaics

In cities with multi-storey construction, roof areas are not sufficient to cover the electricity demand with photovoltaics. Active facade elements make additional areas usable. So far, however, such building-integrated PV modules have rarely been installed. The Advisory Centre for Building Integrated Photovoltaics (BAIP) at the HZB wants to change this.

Corona drug discovery at BESSY II

Corona research at BESSY II: A group of researchers from Lübeck has decoded the virus' main protease. Read how this contributes to the development of drugs. For projects directly related to SARS-CoV-2 we offer a priority FAST TRACK ACCESS.

The athlete in the lab coat

Steve Albrecht is researching on perovskite solar cells and holds several efficiency world records with his team. Back in his schooldays, he was going to become either a competitive gymnast or a scientist. He chose science, but the same athletic ambition still drives his research forward.

The route to BESSY III

At HZB we have the experts for designing and building a new accelerator source, and we have many creative scientists onboard, who are making advancements in the development of photon research. The new source BESSY III is planned go into operation in 2030. Our aim is to offer worldwide unique experiments that will accelerate the gaining of new insights in many disciplines.

Proton Therapy

Patients with eye tumours are being treated with proton beams since June 1998 by  the Charité Universitätsklinikum Benjamin Franklin together with the Helmholtz-Zentrum Berlin. Especially, we succeed to destroy the tumour in more than 97 percent of the patients. Eye tumour therapy with protons


BER II Decommissioning

The Berlin experimental reactor BER II of the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) was finally shut down at the end of 2019. We are currently preparing to decommission the facility.
