Transnational Access

The Mainz Microtron MAMI research infrastructure is a continuous wave electron accelerator, operated by the Institute for Nuclear Physics of the University of Mainz (Germany). It consists of the actual accelerator and major experimental equipment described below. The accelerator consists of two sources for unpolarised and polarised electrons, followed by an injection linac, three consecutive race-track-microtrons and a harmonic double-sided microtron (HDSM) providing a maximum beam energy of 1604 MeV.


The Frascati National Laboratories (LNF), founded in 1955, are the oldest and biggest laboratory of INFN, the Italian agency devoted to fundamental research in nuclear and subnuclear physics and astrophysics. Presently LNF hosts DAΦNE, a high luminosity e+e- collider at 1 GeV c.m. energy (-factory). DAΦNE is a double ring collider of electrons and positrons with 510 MeV energy per beam.


The FTD-ELSA represents a unique combination of infrastructures for hadron physics research and detector development, and includes:

  • the FTD research building with high-grade laboratory space and dedicated instrumentation,
  • the 3.2 GeV electron accelerator ELSA, hosting two hadron physics experiments and a detector test beamline,
  • the Bonn Isochronous Cyclotron, offering 14 MeV/nucleon ion beams mainly for material irradiation.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 824093
