At the Institute of Nuclear Physics, with more than 150 employees, we pursue the goal of fundamentally understanding the properties of hadrons – particles such as the proton or neutron as components of the atomic nucleus – and their interactions. To this end, we operate various large-scale experiments on site and benefit from a variety of experimental and theoretical work groups<\/a> at the institute. <\/p>\n\n\n\n

The most important tool for our research is the electron accelerator MAMI<\/a>, which we have been operating and developing since the 1980s. MAMI is structurally unique worldwide and provides us with high-precision electrons at moderate beam energies. As part of the PRISMA+ cluster of excellence<\/a>, we are also currently building an additional accelerator – MESA <\/a>(“Mainz Energy-Recovering Superconducting Accelerator”) – on the site of the Institute of Nuclear Physics. This accelerator, which is based on the concept of energy recovery, will provide the basis for future high-precision experiments. <\/p>\n\n\n\n

The institute is headed by a managing director from the group of 14 professors, who is elected every three years. <\/p>\n\n\n\n
