Hans J. Specht
The GSI Helmholtzzentrum für Schwerionenforschung mourns the loss of its former Scientific Director Prof. Dr. Hans Joachim Specht, who passed away in Heidelberg on May 20, 2024 at the age of 87. Under the scientific leadership of Prof. Specht, from 1992 to 1999, a rich scientific harvest was obtained at the previously commissioned GSI accelerator facilities UNILAC/SIS/ESR, with numerous discoveries and new technological developments. Professor Specht also played an eminent role in the…

A new nucleosynthesis process denoted the νr-process has been suggested by scientists from GSI Helmholtzzentrum für Schwerionenforschung, Technische Universität Darmstadt, and the Max Planck Institute for Astrophysics. It operates when neutron-rich material is exposed to a high flux of neutrinos. The theoretical proposal, which was recently published in “Physical Review Letters”, may be the solution to a long-standing issue related to the production of a group of rare isotopes present in the…



Hans Geissel
GSI and FAIR mourn the loss of Prof. Dr. Dr. h.c. Hans Geissel * 13.5.1950  † 29.4.2024 who passed away at the age of 73. Hans Geissel was an enthusiastic scientist and gifted experimental physicist, a continuous source of new research ideas, involved in many groundbreaking discoveries in the field of exotic nuclei and other areas of research,awarded numerous scientific prizes and honors, professor at the Justus-Liebig-University Giessen and honorary doctor of Chalmers University in…



The interiour of the ring accelerator SIS18
A new comprehensive simulation study led by GSI/FAIR scientists demonstrates the potential of pulsed electron lenses to significantly increase the highest achievable intensities of heavy-ion beam ring accelerators. This novel space-charge compensation technique is pioneered at GSI/FAIR, where also a prototype is under development. The study, published in Physical Review Letters, paves the way to overcome the so-called space charge limit in ion synchrotrons.



State secretary Judith Pirscher visited GSI/FAIR
The progress of the FAIR project and the ongoing research activities were the focus of a visit to the GSI/FAIR facilities by Judith Pirscher, State Secretary at the Federal Ministry of Education and Research (BMBF). The State Secretary was welcomed by Professor Paolo Giubellino, Scientific Managing Director of GSI and FAIR, and Jörg Blaurock, Technical Managing Director. During her visit, she gained extensive insight into GSI/FAIR’s scientific and technical prospects for the coming decades.



68 girls participated in Girls'Day at GSI/FAIR
The nationwide day of action Girls'Day in 2024 was once again very well received at GSI/FAIR. This time, 68 girls between the ages of eleven and 17 took part in the event and learned about the accelerator facilities and experiments, about research and infrastructure, and especially about the career opportunities at GSI and FAIR. The girls took advantage of Girls'Day to gain insight into the wide range of activities at an international research institution, especially in professions in which…



Ptychographic images of fungal spores
In a new cooperation between the Helmholtz Institute Jena, a branch of GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, and Friedrich Schiller University Jena, a research group is investigating novel imaging methods in the short-wave XUV spectral range. The project will initially run for three years and is being funded by the Free State of Thuringia and the European Social Fund Plus of the European Union with a total of around 900,000 euros, split equally between the partners.



Rudolf Bock
The employees of the GSI Helmholtzzentrum für Schwerionenforschung mourn the death of Professor Dr. Dr. h.c. Rudolf Bock * 21.5.1927     † 9.4.2024 who passed away at the age of 96 after a rich and fulfilling life. Prof. Bock was one of the founding fathers of GSI in 1969. Until his retirement in 1995, he was a member of the Scientific Directorate of GSI and in this function played a decisive role in shaping the scientific profile of GSI. As GSI division head, he pursued the research focus…



Targets used in the experiment
What is the mass of a neutrino at rest? A team led by the department of Klaus Blaum, Director at the Max Planck Institute for Nuclear Physics in Heidelberg, with the participation of Christoph Düllmann's working group at Johannes Gutenberg University Mainz (JGU), the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, and the Helmholtz Institute Mainz has now made an important contribution to the “weighing” of neutrinos as part of the international ECHo collaboration. Using the…
