Upgrade of the RF Readout Electronics of the Cavity Beam Position Monitors at the S-DALINAC* — •Valentin Reichenbach, Michaela Arnold, Uwe Bonnes, Manuel Dutine, Ruben Grewe, Lars Jürgensen, Norbert Pietralla, Dominic Schneider, and Felix Schließmann — Institut für Kernphysik, Technische Universität Darmstadt, Darmstadt, Germany

At the electron accelerator S-DALINAC, cavity BPMs are used for high-precision non-destructive beam parameter measurements. The preexisting RF readout boards have a limited dynamic range. Hence, the existing electronics cannot be used for both low beam current applications (e.g. tuning) and high current experiments without manual adjustments. A new generation of RF boards with a significantly improved dynamic range have been developed in-house, leading to an extensive upgrade of the RF electronics at the S-DALINAC. Within this contribution, the implementation of the new cavity BPM electronics including performance measurements will be presented.
