The therapeutic approach focuses on tailoring the treatment as precisely as possible, taking into account the specific physiological situation of each individual patient. By joining forces, the researchers from HZDR and Monash University aim to optimize the treatment of patients with cancer as well as cardiac and infectious diseases. The goal is to develop new radioimmuno-theranostics: drugs that combine immunotherapeutic and radiotherapeutic approaches.

August: On August 31, the Helmholtz International Beamline for Extreme Fields (HIBEF) at the European XFEL is inaugurated in Schenefeld near Hamburg. Led by HZDR and in cooperation with the German Electron Synchrotron (DESY), HIBEF bundles equipment and expertise from various research institutions to make it available to the international scientific community. The beamline is part of the High Energy Density (HED) experimental station of the X-ray laser European XFEL. It enables deep insights into the structure of materials and into very fast natural processes of plasma physics. Researchers can use it, for example, to improve models of planet formation and to simulate processes in plasmas, thus driving innovation in materials and accelerator research.

September: At a ceremony marking its tenth anniversary, in the presence of Saxony's Minister President Michael Kretschmer, the Helmholtz Institute Freiberg for Resource Technology (HIF) opens a new research infrastructure for recycling strategic metals on a pilot scale. With the metallurgy pilot plant, the HZDR institute, which cooperates closely with the TU Bergakademie Freiberg, is significantly expanding its research expertise in the fields of metallurgy as well as recycling and thus in the circular economy.

December: HZDR Innovation GmbH is expanding its high-energy ion implantation capabilities with a new site in Trnava. For about ten years, the HZDR has been providing industry with fast and direct access to the facilities at the Ion Beam Center through its transfer company. After the Dresden-based company and its partners in Trnava upgraded an accelerator at the Slovak University of Technology in Bratislava, companies can now refine wafers for power electronics in Slovakia.


February: Molybdenum (Mo-99) plays a crucial role in the diagnosis of cancer and other diseases. The radioisotope decays after a few hours into technetium-99m, which is applied in imaging techniques worldwide. However, the current fission-based manufacturing process has challenges, such as aging reactors and environmental pollution. Researchers are therefore looking for alternatives for production. At HZDR, the European SMART collaboration has successfully tested the production of Mo-99 utilizing the superconducting linear accelerator ELBE. Because molybdenum-100 is used as the starting material, there is no need to fission heavy uranium, unlike in nuclear reactors. This also means that less radioactive waste is produced - especially hardly any with a long half-life.

March: A research team led by the HZDR has successfully tested irradiation with laser protons in an animal model for the first time. With such fast protons, tumors can be irradiated more effectively and more gently than with X-rays. However, the modern form of therapy with protons requires large particle accelerators. Experts are therefore investigating alternative accelerator concepts - for example, systems in which a laser accelerates the protons. In preclinical studies, they should help pave the way for optimal radiation therapy.

April: The Center for Advanced Systems Understanding (CASUS) becomes the ninth HZDR institute. Using new digital methods, questions on complex topics such as the energy transition or climate change are addressed in Görlitz. Researchers at CASUS develop digital solutions that can be applied in disciplines as diverse as climate and environmental research, systems biology or astrophysics, where they help to answer relevant scientific questions. CASUS' expertise is also needed to be well positioned in future topics such as artificial intelligence, supercomputing and open-source research software. CASUS will work together with partners Helmholtz Centre for Environmental Research Leipzig, Max Planck Institute for Molecular Cell Biology and Genetics, Dresden University of Technology and the University of Wrocław.

July: The Department of Theoretical Physics, launched in 2018, is transformed into the now tenth institute of the HZDR. The research work focuses on non-equilibrium phenomena. These can be, for example, effects under extreme conditions, from strong laser fields to the environment of a black hole, or in the early universe. The scientists explore the physical foundations, from which other institutes at HZDR benefit when planning and conducting experiments.

December: Free-electron lasers (FELs) generate very intense light pulses. Particularly in the X-ray range, they can help analyze a wide variety of materials in detail and to track ultrafast processes with great precision. Until now, the facilities have been based on conventional electron accelerators, making them long and expensive. An international team at HZDR has achieved a breakthrough on the way to a more cost-effective variant: It was able to implement an FEL with a still young technology - laser plasma acceleration. In the future, this will make it possible to build much more compact systems, which would significantly expand the range of applications for FELs.
