A climate-neutral century needs better materials.

What happens inside a battery the moment it fails? How do electrons dance across a quantum material?

For over 40 years, Berlin has been a global hub for soft X-ray synchrotron science to solve such pressing questions. With BESSY III, we are building a world-class super-microscope to decode the high-tech materials of the future.

Simply brilliant!

The next generation light source for society

BESSY III is a 4th generation light source that will be a thriving hub for joint discovery. We bring together advanced technology and top experts to solve the world’s biggest challenges. To do so, 3 facts build a unique research and development environment:

01

Brilliant soft X-rays

A source optimised for the energy range where chemistry happens. It’s the ultimate tool to watch materials action in real-time.

02

“Gold Standard” for research and industry

Teaming up with Germany’s top measurement experts on site, we offer the reliable, rock-solid data that industry and science need to build the future.

03

Berlin-Adlershof: the biggest connected Campus in Germany

Based in one of Germany’s top high-tech parks and the vibrant research landscape in Berlin, we bring scientists and companies together to crack complex problems under one roof.

Six questions.
One light source.

A Driver for Germany’s green and digital future
