MAGIX Experiment Overview

The MAinz Gas Injection Target EXperiment MAGIX will use the ERL mode of MESA. The electron beam provided interacts with the MAGIX gas jet target in the scattering chamber, which is connected to the beam pipe without any windows. Exploiting the high beam current of MESA and the low density of the gas jet target, luminosities on the order of 1035cm-2s-1 are achieved. To maintain the vacuum in the system, the gas jet is pumped out by a cascade of vacuum pumps immediately after interaction with the electron beam.

The scattered beam electrons pass through two identical magnetic spectrometers before being detected by the focal plane detectors, which are a time projection chamber and a trigger veto system for each spectrometer.

In order to also detect recoil particles of the gas jet, a silicon strip detector is placed in the scattering chamber.

The relatively low beam energy limits the energy of the scattered particles, so the entire system is optimized to limit the interaction of secondary particles before their detection.
