description

MAMI, the MAinz MIcrotron, has become a synonym for a cw electron scattering facility in the 1.5 14;GeV range with an outstanding beam quality and reliability. The Institute for Nuclear Physics (IKP) at the Johannes Gutenberg-University of Mainz, the home of MAMI, has developed and built this cascade of four recirculating machines for precision scattering experiments mostly with polarized electrons and photons for research in the field of hadron and nuclear physics. The central physics topic is the investigation of strongly interacting systems with the electroweak probe. This field, nowadays called strong QCD, which means QCD in the strongly coupled, non perturbative regime, still poses a number of fundamental questions. The emergence of hadrons with their masses, charges, magnetization, and flavors, together with the corresponding spatial distributions, is not yet fully understood and still very far from precise predictions. This is also true for the response of hadrons to external fields known as polari...
