The MAGIX StarryNight calibration system — •Daniel Steger for the MAGIX collaboration — Institute of Nuclear Physics, JGU Mainz

The MESA accelerator will host the MAGIX experiment, which is based on the scattering of an electron beam on a gas jet target. This enables scattering on gases like hydrogen while minimizing interaction with any other materials allowing us to perform high precision experiments. The measurement of the scattered particles is done by two magnetic spectrometers using a GEM based TPC to track the particles. To achieve the precision desired an independent system to calibrate the TPC is necessary. A prototype of such a system has been designed, utilizing LEDs with a wavelength of 275 nm that are operated in pulses above the cathode of the active volume of the TPC. Furthermore the cathode of the TPC has been replaced with aluminium based photon-electron-converter boards.

In this contribution the setup and development of this calibration system will be presented.
