Description
The new MAGIX experiment, to be built at the 105 MeV line of the ERL MESA at the institute for Nuclear Physics of the University of Mainz, features two high-resolution spectrometers looking at the target area where luminosity of the order of $10^{35} \text{cm}^{-2}\text{s}^{-1}$ will be achievable. To improve the momentum and angular resolution of the spectrometers, the greatest challenge is to minimise the material budget of their GEM-based focal plane detectors as much as possible.
In this talk we will present the solutions we developed to build a high-resolution MPGD tracker for those experimental conditions including a foil based readout plane with Chromium-GEM amplification and a short-drift TPC with an open field cage, the latter being the solution finally approved for the experiment.
