International team at HIM awarded “Erwin Schrödinger Prize — Science Award of the Stifterverband”

Joint Press release with GSI/JGU


An international team at the Helmholtz Institute Mainz (HIM), a branch of the GSI Helmholtzzentrum in cooperation with the Johannes Gutenberg University Mainz (JGU), has received the “Erwin Schrödinger Prize — Science Award of the Stifterverband” of the year 2021 for important advances in the field of magnetic resonance imaging (MRI). The award ceremony took place during the Helmholtz Annual Meeting in Berlin. “The Science Award of the Stifterverband rewards scientifically or technically innovative achievements that have been made in frontier areas between different subjects of medicine, natural sciences and engineering. This curiosity and the will to join forces across borders also characterize our award winners today," said Professor Michael Kaschke, President of the Stifterverband, in his laudatory speech. The award ceremony was originally scheduled to take place in December 2021, but was postponed due to the Corona situation.


Professor Paolo Giubellino, Scientific Managing Director of GSI and FAIR, was also pleased about the scientists’ recognition: “The Helmholtz Institute Mainz offers the researchers in this interdisciplinary collaboration an environment to enable top performance. The results of this outstanding research team demonstrate the overriding importance of close global networking in the scientific community. I am therefore delighted that this great scientific achievement has been honored with the Erwin Schrödinger Prize.”


The group led by Professor Dmitry Budker, professor of Experimental Atomic Physics at JGU and Section Head at HIM, developed a technique to improve hyperpolarized magnetic resonance imaging. The new technique for observing metabolic processes in the body promises to be much cheaper and simpler than previous methods. MRI, or magnetic resonance imaging, has become a standard method for medical examinations in recent decades. It can be used to examine soft tissues of the body such as the brain, intervertebral discs or even the formation of tumors.


The Erwin Schrödinger Prize 2021 went in detail to Dmitry Budker (physicist, HIM), James Eills (chemist, HIM), John Blanchard (chemist, HIM), Danila Barskiy (physical chemist, HIM), Kerstin Münnemann (chemist, University of Kaiserslautern), Francesca Reineri (chemist, University of Turin), Eleonora Cavallari (pharmaceutical and biomolecular scientist, University of Turin), Silvio Aime (biological scientist, University of Turin), Gerd Buntkowsky (physical chemist, TU Darmstadt), Stephan Knecht (physicist, TU Darmstadt and NVision, Ulm), Malcolm H. Levitt (chemist, University of Southampton) and Laurynas Dagys (chemist, University of Southampton). The prize is endowed with a total of 50,000 euros.


The Helmholtz Institute Mainz was founded in 2009 by GSI and JGU to further strengthen the long-standing cooperation between the two institutions. At its location in Mainz, HIM addresses questions concerning the structure, symmetry and stability of matter and antimatter in experimental and theoretical investigations. Basic funding is provided by the federal government and the state of Rhineland-Palatinate. The JGU supports HIM by providing infrastructure. (CP)

Mainzer Science Week

Vom 12. bis 18.09.2022 fand die 4. Mainzer Science Week statt, die von der Mainzer Wissenschaftsallianz und der Landeshauptstadt Mainz veranstaltet wurde. Die Forschungssektion SPECF (Spectroscopy and Flavour) des HIM hat sich mit zwei Veranstaltungen beteiligt.


Eine unterhaltsame und lehrreiche Fahrt erlebten die Gäste der Mainzer Science Tram am 16.09.2022. Verschiedene Mainzer Wissenschaftler:innen brachten ihnen auf der Rundfahrt durch Mainz ganz unterschiedliche Forschungsgebiete näher. Mit dabei war auch Professor Achim Denig vom HIM / Institut für Kernphysik mit seinem Vortrag „Quarks & Co – Die fabelhafte Welt der kleinsten Teilchen“. Mit einem Augenzwinkern wies er das Publikum zu Beginn darauf hin, dass es in dem Vortrag natürlich nicht um (Speise)quark gehen soll, sondern um die Bausteine, aus denen sämtliche Materie, egal ob Menschen, Galaxien oder eben Speisequark, zusammengesetzt ist. In den vergangenen Jahrzehnten ist es in der Kern- und Teilchenphysik gelungen, die Grundbausteine der Materie – die sogenannten Elementarteilchen – zu identifizieren und ihre Wechselwirkung untereinander im Standardmodell der Teilchenphysik zu beschreiben. Zu diesen elementaren Teilchen gehören eben auch die Quarks, die in sechs Sorten existieren und die die Grundlage für die Protonen und Neutronen bilden.


Das Standardmodell konnte einerseits auf sensationelle Art und Weise bestätigt werden, jedoch gibt es noch viele offene Fragen, wie Denig seinem Publikum in der Science Tram erzählte: So z. B. ob es noch weitere bisher unentdeckte Teilchen gibt, die eine Erweiterung des Standardmodells erfordern? Oder warum die bekannten Teilchen extrem unterschiedliche Massen haben und weshalb sie als kleinste Bausteine unseres Universums überhaupt genau diese Massen besitzen und nicht etwas schwerer oder leichter sind? Laut Professor Denig wird es daher ein großes Ziel der kommenden Jahre sein, die fabelhafte Welt der Teilchen nicht nur qualitativ, sondern auch quantitativ besser zu verstehen. Die Mainzer Beschleuniger MAMI und zukünftig MESA werden zur Beantwortung dieser Fragen wichtige Beiträge liefern.


Am Samstag, dem 17.09.2022 konnten ca. 30 Interessierte den Teilchenbeschleuniger MAMI (Mainzer Mikrotron) kennenlernen. Professor Achim Denig und Stephan Aulenbacher vom Institut für Kernphysik stellten den weltweit einzigartigen Teilchenbeschleuniger vor, der sich mit seinen einzelnen Beschleuniger-Einheiten 11 Meter unterhalb der Erde in einem weitflächigen Areal der Johannes Gutenberg-Universität Mainz befindet.

Using quantum sensor technology to improve brain tumor operations

Quantum technology on its way into society: In the joint project DiaQNOS, researchers from JGU and the Helmholtz Institute Mainz are developing quantum sensors to improve brain tumor surgery.


Removing a brain tumor presents surgeons with special challenges: They must remove the tumor, but without damaging healthy brain tissue. Among other things, it is important to keep an eye on the motor cortex, which is responsible for movement. If, for example, a nerve pathway leads from this to the arm, it must not be severed, because otherwise the patient will no longer be able to move the arm after the operation. Appropriate diagnostics are already helping to identify and spare such nerve tracts and brain regions.


DiaQNOS: Lighthouse project in quantum sensor technology


In the future, quantum sensor technology is expected to further improve the assignment of functions to certain brain areas - via new diagnostic devices that, among other things, refine neuronavigation. A consortium of the Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) is working on this in the DiaQNOS project together with various partners from research, medicine and industry. The five-year project, which started in October 2022, is funded by the German Federal Ministry of Education and Research (BMBF) with a total of almost eleven million euros; JGU, as project leader, will receive 1.5 million euros.

The basis for the project was laid by the collaborative project BrainQSens: here, a consortium in which JGU was also represented developed highly sensitive magnetic sensors that enable improved medical diagnostics. "In this flagship quantum sensor project, we have already been able to improve the magnetic field sensor technology to such an extent that, in principle, magnetic fields of the brain can be registered with it," explains Dr. Arne Wickenbrock from JGU or HIM, who coordinates the joint project. "Now it's a matter of taking the next steps on the way to medical application and making quantum sensor technology useful for society." The consortium reflects this application focus in that, in addition to neurosurgeons from Freiburg University Hospital, i.e. the technology's eventual users, medical device manufacturer inomed Medizintechnik GmbH is also represented. In addition, Sacher Lasertechnik GmbH and TTI GmbH are contributing their expertise, i.e. companies with experience in the commercialization of new developments.

A device suitable for use in surgery is to be developed over a period of three years, followed by two years of medical research. Among other things, brain tissue from a tissue database in Freiburg will be examined for the first time for its magnetic properties, especially with regard to new diagnostic possibilities for brain tumors.


Mainz expertise in the construction of a quantum sensor


Among other things, the researchers from JGU and HIM are dedicated to building the quantum sensor; after all, Prof. Dr. Dmitry Budker's research group has strengthened magnetography as a core competence in Mainz, and he is also allowing his expertise to contribute to the project. "These quantum sensors are based on nitrogen vacancies in diamonds - nanoscale magnetic field sensors confined in the diamond. A huge number of these magnetic field sensors can exist in a thin layer of diamond. This makes it possible for us to create a magnetic image of the object that the sensor sees," Wickenbrock explains. Nerve communication in the human body works via electrical charges that whiz through the nerve pathways. Now, every moving charge generates a magnetic field - so there are numerous magnetic fields in the human body, including in the brain. The sensor is designed to detect and analyze these and thus tell the surgeons more about the function of the respective brain areas. This will enable physicians to plan the incision path more precisely and in a way that is gentler on the patient.
