Silicon strip detector set-up for α-particle detection at MAGIX — •Jennifer Geimer for the MAGIX collaboration — Institut für Kernphysik, Johannes Gutenberg-Universität, Mainz, Germany

The MAGIX experiment will take place at the energy recovering superconducting electron accelerator MESA in Mainz. At MAGIX high-precision electron scattering experiments will be performed. The experimental set-up is currently under development, it comprises a windowless gas target and two identical high-resolution magnetic spectrometers including a GEM-based TPC. Additionally, a silicon strip detector is planned to detect recoil particles in the scattering chamber. Its resolution requirements are derived from simulation studies of the ¹⁶O(γ*,α)¹²C reaction, which we will examine to determine the S-factor of the nucleosynthesis reaction of carbon and alpha. The design of this detector system and first performance studies will be presented in this talk.
