Development of large scale focal plane detectors for MAGIX
MAGIX is a planned experiment that will be implemented at the upcoming accelerator MESA in Mainz. Due to its location in the energy-recovering lane of the accelerator beam-currents up to 1 mA with a maximum energy of 105 MeV will be provided for precision experiments.MAGIX itself consists of a jet-target and two magnet-spectrometers. Inside the spectrometers GEM-based detectors will be used in the focal plane. The design goals for the detector modules are a spatial resolution of 50 μm, a size of 1,20 x 0,30 m² and a minimal material budget. To accomplish these goals we started developing several GEM-prototypes to study different behaviors and techniques for the final detector. The GEMs used are provided by CERN and are trained, stretched and framed in our laboratory. In this contribution the requirements, ongoing development and achieved measurements are presented.
