A1 - Electron Scattering

The physical program of the A1 collaboration with its 50 members from 20 countries is focused on hadron structure.

A2 - Real Photons

A photon incident on a nucleon couples to the nucleon electromagnetic current causing it to radiate mesons if the photon energy is sufficiently high.

A4 - Parity Violation

The atomic nucleus is a bound state of protons and neutrons (so called nucleons). The A4 collaboration is investigating the structure of these nucleons.

X1 - X-Ray Radiation

The X1 collaboration develops at MAMI brilliant novel radiation sources, and explores their potential for applications.
