The MAGIX Trigger Veto System — •Sebastian Stengel for the MAGIX collaboration — Johannes Gutenberg University Mainz, Institute for Nuclear Physics, Germany

The MAGIX setup will be used for Dark Photon searches using the visible as well as the invisible decay channel. The MAGIX trigger veto system will enable the fast timing characteristics needed for investigating the visible Dark Photon decay channel A* -> e+e-. It will further be used for energy-loss measurements and will provide the basic hit and position information for the triggered readout of the MAGIX time projection chamber. The MAGIX trigger veto system will consist of one segmented trigger layer of plastic scintillator bars and a flexible veto system of additional scintillation detectors and lead absorbers placed beneath the trigger layer. The data readout will use the ultrafast preamplifier-discriminator NINO chip developed for use in the ALICE detector followed by FPGAs programmed as TDCs.
