Dr. Yannik Zobus, a laser physicist at GSI/FAIR in Darmstadt, is head of the LASE-FUSE (LAser Simulation for Enhanced FUSion Efficiency) Young Investigators Group since May 1, 2026. As part of the “Fusionstalente” (fusion talents) funding program of Germany’s Federal Ministry of Research, Technology, and Space (BMFTR), the project will receive three million euros in funding over five years. Thus, already for the second time a GSI/FAIR project is awarded in the framework of the BMFTR initiative.

After the fire that occurred in the area of the high-voltage electrical power supply system of the UNILAC linear accelerator at the GSI Helmholtzzentrum für Schwerionenforschung in early February 2026, the on-site investigation into the cause of the fire has now been completed. Over the past few weeks, the Hessian State Criminal Police Office conducted the relevant investigations and determined that a probably technical defect within a control cabinet was the cause of the fire. This confirms…

An international research team has achieved an important milestone for astrophysics at GSI/FAIR in Darmstadt: In the CRYRING@ESR storage ring, scientists were able to measure nuclear reactions at extremely low energies for the first time, mirroring the conditions inside stars. This novel experimental approach lays the foundation for decoding the formation of elements in the universe with even greater precision in the future.

Girls’Day at GSI/FAIR was again a huge success this year. Sixty-nine schoolgirls aged eleven to seventeen participated and explored the international research center, the accelerator facilities and experiments, as well as the technical infrastructure. Girls’Day is a nationwide event designed to encourage girls to learn about careers where women have traditionally been underrepresented.

The GSI Helmholtzzentrum für Schwerionenforschung and the international accelerator facility FAIR have made an important contribution to the success of the Artemis II Moon mission. A camera specially developed for use in space was successfully tested in advance under realistic conditions at the GSI and FAIR particle accelerator. The camera — a specially modified model of the Nikon Z9 — was subjected to extensive radiation testing by NASA at the GSI/FAIR particle accelerator in March 2025. During…

The CBM Collaboration awarded two young researchers with the "CBM Best Thesis Award" for outstanding PhD theses. The awards were recently presented during the CBM Collaboration Meeting and honored Dr. Dario Ramirez and Dr. Pavish Subramani. The Compressed Baryonic Matter (CBM) experiment is one of the central research pillars of the international accelerator center FAIR, which is currently being built at GSI.

An international research team has found evidence of the existence of an exotic atomic nucleus state in an experiment at the GSI/FAIR research center in Darmstadt. Although such a state has long been predicted theoretically, it has never been observed before. The system consists of an atomic nucleus of the carbon isotope ¹¹C and an η′ meson (etaprime meson) — a short-lived particle composed of a quark and an antiquark. This system is bound exclusively by the strong interaction, i.e., the force…

FAIR and GSI mourn for Prof Guenther Rosner, a passionate physicist, co-founder of FAIR and relentless supporter of the FAIR project. He passed away on 21 March 2026 in the age of 77 years.

The student space association TU Darmstadt Space Technology e.V. (TUDSaT) has successfully completed the assembly of the TRACE satellite in the cleanroom environment of GSI/FAIR’s detector laboratory. The satellite also carries detectors from GSI/FAIR, which are designed to measure charged particles in orbit.
