Characterization of the MAGIX windowless gas jet target in high-intensity electron beams — •Maximilian Littich for the MAGIX collaboration — Institut für Kernphysik, Johannes Gutenberg-Universität Mainz, Deutschland

MAGIX is a fixed target electron scattering experiment at the upcoming MESA accelerator. It will be operated in the energy recovery linac mode of the accelerator which allows to reach beam currents of at least 1 mA. This operation mode requires a very thin target for which MAGIX will use an internal, windowless gas jet target. This cryogenic supersonic gas jet target will be able to run with different gases, e.g. hydrogen, deuterium, helium, oxygen, argon or xenon.

At the existing A1 multi-spectrometer facility at the electron accelerator MAMI detailed studies have been carried out using hydrogen as the target gas. This talk will show the results of these studies, the challenges of the operation and the performance of the target under real beam condition.
