Mainz Microtron MAMI

The Mainz Microtron is the central research facility for experiments at the Institute for Nuclear Physics. It is an accelerator complex which at its present stage, MAMI C, supplies an electron beam with a maximum energy of 1558 million electron-volts (MeV). Some of the many outstanding qualities of MAMI include the high beam current of up to 100µA, an excellent energy spread of less than 10-4, as well as its extremely high reliability, with more than 7000 beam time hours in the year 2008. The stage MAMI C, operating since 2007, is a world-wide unique harmonic double-sided microtron (HDSM), which is connected to a cascade of altogether three racetrack microtrons. An important aspect of the MAMI accelerator is the potential to operate with polarized beams with a polarization of up to 80%, thus allowing for simple-and double-polarization experiments at all experimental setups at the Institute for Nuclear Physics.
