Interior of a new UNILAC buncher
Two radio-frequency buncher cavities for GSI/FAIR's UNILAC linear accelerator have recently been delivered. They are used to shape the ion beams during transfer to the poststripper section (Alvarez structure) and are essential for longitudinal matching to achieve low-loss acceleration and good beam quality, especially at high intensities. The two bunchers, with operating frequencies of 36 and 108 MHz, are intended to replace the existing devices, which have been in operation for about 25 years,…

Prof. Dr. Hannah Elfner
GSI scientist Prof. Dr. Hannah Elfner is appointed Senior Fellow at the Frankfurt Institute for Advanced Studies (FIAS). She made it into this highest category at the theoretical research institute FIAS - comparable to a W3 professorship at the university.

Radon chamber at GSI.
Anti-inflammatory, therapeutic effects, but also risks - the radioactive noble gas radon contains both at the same time. Radon and especially its short-living progeny are considered to be responsible for about half of the annual radiation exposure from natural sources and are classified as carcinogenic. Researchers from the GSI Helmholtzzentrum für Schwerionenforschung now have proven in a paper published in the “International Journal of Environmental Research and Public Health” that face…

Measurement setup SHIPTRAP for research on the physics of superheavy elements
In a review article in the diamond jubilee issue of the journal “Radiochimica Acta”, researchers from GSI/FAIR, the Helmholtz Institute Mainz, and Johannes Gutenberg University Mainz report on highlights of the research on superheavy elements (SHE) carried out at GSI over the past five decades. The article focuses on the discovery of the “superheavies” and on chemical studies addressing the placement of the new, heaviest elements in the periodic table of elements.

Prof. Hans-Jürgen Wollersheim
Professor Hans-Jürgen Wollersheim has been awarded an adjunct professorship at the University of Delhi for his many years of cooperation with Indian scientists. Since 2004, the GSI researcher has engaged in intensive scientific cooperation with India and was the liaison person for the cooperation with India in the FAIR project as In-Kind Coordinator FAIR@GSI.

Delivery of the coldbox for the FAIR cryo facility
A large heavy goods transport set off from Aschaffenburg to Darmstadt on November 30, 2022. Its destination was the international accelerator facility FAIR (Facility for Antiproton and Ion Research), which is currently being built at the GSI Helmholtzzentrum für Schwerionenforschung. Loaded was the so-called “coldbox”, a steel tank with a length of 18 meters, a height of more than 4.5 meters and a weight of 85 tons. The coldbox is the heart of the cryogenics facility, produced and installed by…

Screenshot from the videoconference
Similar to the past two years, GSI/FAIR participated in the online event series “Saturday Morning Physics” for high school students, hosted by the Technical University Darmstadt. The approximately 220 participants were informed about the accelerators and experiments at GSI as well as the FAIR facility which is currently under construction during a virtual tour.

Peter Micke
Peter Micke will be Helmholtz Young Investigator Group Leader at the Helmholtz Institute Jena, a branch of the GSI Helmholtz Center in Darmstadt. He will receive 1.5 million euros over the next five years to set up his experiment at the GSI accelerator facility. He intends to use novel quantum technology at the HITRAP facility at GSI for high-precision measurements of heavy highly charged ions. The combination of a heavy ion accelerator and those kinds of precision experiments is unique.

Test facility THOR at the University of Salerno.
The future FAIR ring accelerator SIS100 uses superconducting magnets for deflection, focusing and correction of the circulating ion beams. While the complete series of dipole modules required for beam deflection has already been manufactured and tested, series production of the quadrupole modules required for focusing and correction is still in an earlier phase. In the meantime, an important step has been taken with the commissioning of the cryogenic test facility THOR...
