The Silicon Strip Detector setup for the MAGIX Experiment — •Jennifer Geimer for the MAGIX collaboration — Institute for Nuclear Physics, Mainz, Germany

The MAGIX-Experiment (Mainz Gas Injection Target Experiment) will be a high precision electron scattering experiment located at the MESA accelerator at the Institute for Nuclear Physics in Mainz. The experimental setup comprises a windowless gas jet target which allows direct interaction between beam electrons and target nuclei. It can be operated with different types of target gas and therefore allows investigation of a wide physical program. While the scattered electrons will be detected by two magnet spectrometers, the detection of nuclear fragments of the target will be done by using several recoil detectors. The centerpiece of the recoil detector design is a Silicon Strip Detector with size of 50 x 50 mm². To completely stop protons with an energy of O(70 MeV), the silicon detector will be equipped with an additional plastic scintillator layer read out by silicon photomultipliers. The channels of the silicon detector as well as the silicon photomultipliers will be processed by the APV25 Chip, while the trigger signal is simultaneously produced using an additional frontend board.
This presentation gives a short overview of the MAGIX experiment and the resulting design parameters for the recoil detector. It focuses on the working principle and the current state of development of the Silicon Strip Detector.
