The GSI researchers Gottfried Münzenberg and Hans Geissel have discovered the largest number of atomic nuclei. Münzenberg, a professor at Johannes Gutenberg University Mainz, holds the world record with a total of 218 atomic nuclei. Geissel, a professor at Justus Liebig University Giessen, holds second place with 210 nuclei. That’s the result of a count carried out by Michael Thoennessen, a researcher at Michigan State University in the USA. He is currently working on the history of the...

The heavy ion cancer therapy developed at GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt has proved very successful. Thus far, however, it has primarily been used to treat brain tumours. This is because the head is one part of the body that can be kept completely stationary – a prerequisite for the ion beam, which hits cancer cells with pinpoint precision. Breast or stomach tumours are extremely frequent but more difficult to treat with an ion beam as they move as a result of...

In a new research project lead-managed by GSI the anti-inflammatory therapeutic properties and the risks of a therapy with radon will be studied. The German Federal Ministry of Education and Research funds the project Grewis (Genetische Risiken und entzündungshemmende Wirkung von ionisierender Strahlung, meaning genetical risks and anti-inflammatory properties of ionizing radiation) with three million Euro in the next 3,5 years. Research partners of GSI are the technical university in Darmstadt,...

Babcock Noell GmbH
GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt, Germany, has placed an order with Babcock Noell GmbH for the manufacture and supply of 113 superconducting high-tech magnets for the accelerator facility FAIR. The magnets, each of which weighs more than a ton, are required for the central ring accelerator SIS100, the heart of the FAIR facility. This ring accelerator will accelerate charged particles to almost the speed of light for the various experiments at FAIR. The magnets that...

The FAIR international accelerator center in Darmstadt is one of the largest projects for basic research in physics worldwide. A key phase of the project commenced today when Dr. Helge Braun, the Parliamentary State Secretary of Germany’s Federal Ministry of Education and Research, presented GSI Helmholtzzentrum für Schwerionenforschung GmbH with the approval for €50.2 million in project funding. As a result, orders can now be placed for the series production of key components for the FAIR...

FAIR GmbH/GSI Helmholtzzentrum für Schwerionenforschung GmbH
On December 5, 2011, workers began preparing the construction site for the planned particle accelerator facility FAIR (Facility for Antiproton and Ion Research). The new facility will be located close to the GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt. The parks and gardens authority of the city of Darmstadt, a center of scientific research, had approved the preparation of the site in November.

More and more aspects of our daily life require high performance computers. These use a lot of energy. New energy-efficient computer concepts to protect the environment and save costs are therefore necessary. A new environmentally friendly computing center of highest performance, the Green Cube, will now be built at GSI. Scientists from all over the world want to use it for the enormous amounts of data collected from experiments at the future accelerator facility FAIR . With FAIR they expect to...

In a successful test conducted at the GSI Helmholtzzentrum a group of scientists used the PHELIX high-performance laser to accelerate hydrogen ions to about ten percent of the speed of light. This makes GSI one of the few research centers worldwide that can accelerate particles not only with conventional technology using high voltage electricity, but also with lasers. The test was carried out under the direction of a group of scientists from TU Darmstadt. Scientists now want to use the facility...

With the ion trap Shiptrap scientists at GSI have measured the mass differences of specific atomic nuclei with highest precision; these nuclei are potential candidates for an extremely rare neutrinoless radioactive decay mode. They identified the isotope gadolinium-152 as the most appropriate nucleus to date to observe this decay mode that will provide new insight about neutrinos.
