Deutsches Elektronen-Synchrotron DESY is a world leader in particle and X-ray light research

Deutsches Elektronen-Synchrotron DESY is one of the world's leading scientific centers, specializing in basic and applied science using particle accelerators. Based in Germany, DESY is a key player in the international scientific community, providing access to cutting-edge infrastructure projects to scientists from around the globe.

DESY scientific mission

The main goal of DESY is to promote knowledge about the structure of matter, the structure of the Universe and the creation of innovative technologies. The center works in several key areas:

• Particle physics - the study of elementary particles and their interactions to understand the basic laws of nature.
• Particle astrophysics - analysis of cosmic rays and other “messengers” of the Universe to study high-energy processes outside the Solar System.
• Photon research - the use of powerful X-ray sources to study the structure of materials at the atomic level.
• Innovation and technology transfer - application of scientific discoveries in medicine, industry and new materials.

PETRA IV: a new era of scientific discovery

One of DESY's most significant projects is PETRA IV - a super-powerful "discovery machine" capable of generating extremely bright and short-lived X-rays. This source allows scientists to observe the dynamics of chemical reactions, the structure of complex molecules and processes at the nanoscale with unprecedented accuracy. PETRA IV opens new horizons in basic science and applied research.

Key infrastructure facilities

DESY operates a number of global research facilities:

• European XFEL (European X-ray Free Electron Laser) is one of the most powerful X-ray light sources in the world, allowing real-time “filming” of molecular processes.
• PETRA IV is the next generation of accelerator, focused on the highest resolution.
• Other accelerators and instruments for the study of materials, biomolecules and quantum phenomena.

International cooperation and openness

DESY actively cooperates with universities, research centers and industrial partners around the world. Its research platforms are accessible to scientists from any country. All data obtained is published openly, which contributes to the progress of science both in Germany and abroad.

Scientific achievements and current news

In August 2025, DESY celebrated important events:

• Memorable date - the 100th anniversary of the birth of the outstanding physicist Herwig Schopper, one of the founders of the modern European scientific community.
• DESY scientists, together with colleagues from European XFEL, have created a new form of gold with unique properties - an important step for the development of new materials.
• For the first time, quantum fluctuations in complex molecules have been directly observed, expanding our understanding of quantum physics.

Career and education at DESY

The center actively attracts young researchers and students. The site offers programs for schoolchildren, internships, and job opportunities in science and engineering. DESY makes its work accessible to people with different levels of training - including special versions of the site in easy language and in sign language.
