Welcome to the Institute for Nuclear Physics

The Mainzer Microtron MAMI, an electron accelerator for energies of up to 1,6 GeV, is the core of experimental investigations. Additionally, scientists at the Institute of Nuclear Physics are working on the theoretical description and interpretation of the experimental results and of external experiments in, for example, Beijing (IHEP), Darmstadt (GSI) and Geneva (CERN).

New technology for generating high-energy gamma radiation

On 1 June 2022, the EU-funded project TECHNO-CLS started with the participation of the X1 collaboration of the Institute of Nuclear Physics. Eleven partners from Germany, Italy, Great Britain, France, Greece and Belgium are researching how to generate high-energy gamma radiation by exposure so-called oriented crystals with ultra-relativistic charged particles. The aim is to achieve photon energies of up to GeV, which is equivalent to radiation wavelengths of up to a few femtometres. So far, it has not been possible to generate such extremely short-wave radiation with existing radiation sources. From an experimental point of view, however, it promises access to unprecedentedly small structures and is thus of particular importance for research and applications in the field of nuclear and solid-state physics as well as the life sciences.

The TECHNO-CLS consortium combines theoretical, computational, experimental and technological contributions. The central task, which is being worked on at the Institute of Nuclear Physics, is the provision of a relativistic high-quality positron beam of low emittance. Such positrons can be guided over longer distances in crystals, whereby the intensity of the radiation produced there can be significantly increased by coherent effects, similar to a magnetic undulator. In addition, a case study will investigate whether positrons can also be accelerated from the source with the existing MAMI accelerator facility. This would open up the possibility of generating positron beams with the intensity and quality of the electron beam used so far in MAMI.

Photon-photon interactions in the Standard Model and beyond: New research unit at JGU granted DFG funding

https://www.uni-mainz.de/presse/aktuell/bilder/logo_photon-photon_interactions.jpgA pure quantum effect as the key to a better understanding of the subatomic world / New research program in Mainz bundles a wide range of expertise

In classical physics, the superposition of light waves resulting in interference is a well-known phenomenon. An interaction of light rays in the sense of a scattering is, however, classically impossible. Conversely, in the subatomic world, which is described by quantum effects, the quantum particles of light – known as photons – do indeed interact with each other. ...

International Physics School on Muon Dipole Moments and Hadronic Effects -- in Memoriam Simon Eidelman – with more than 70 participants organized by JGU Mainz

The concept of this school was to bring together young researchers involved in the global effort of investigating the large excess of the measured value of the muon anomalous magnetic moment over the Standard Model prediction. Earlier this year, the Muon g-2 experiment at Fermilab released their long-awaited result which, to everyone's excitement, showed a strengthening of the discrepancy with the Standard Model (in total 4.2 standard deviations). This result fortified both the possibility of New Physics and the strong interest in this school. ...

Further security measures at KPH to protect against the coronavirus

Effective immediately the automatic door opener at the Institute will be deactivated after 12 pm. At which time the Institute will only be accessible to people who have an RFID transponder/key. Access for people outside of the Institute (guests, other JGU employees, etc.) should only be limited to essential, work-related needs.
