Studies on a Three-Turn Energy-Recovery Mode at the S-DALINAC — •Felix Schliessmann, Michaela Arnold, Adrian Brauch, Manuel Dutine, Marco Fischer, Ruben Grewe, Lars Juergensen, Maximilian Meier, Norbert Pietralla, and Dominic Schneider — Institut für Kernphysik, Technische Universität Darmstadt, Schloßgartenstraße 9, 64289 Darmstadt, Darmstadt, Germany

The electron accelerator S-DALINAC at Technische Universität Darmstadt was successfully operated in one-turn and two-turn energy-recovery mode. Due to its existing third recirculation beamline, the S-DALINAC has the potential to be operated in three-turn energy-recovery mode. In this mode, an accelerated and a decelerated beam are superimposed in both the first and the second recirculation beamline. Due to this shared beam-transport, this mode is particularly challenging since the number of degrees of freedom is reduced compared to an individual beam-transport. Therefore, beam-dynamics simulations are necessary to determine a suitable setup in advance. In this contribution, results of these beam-dynamics simulations will be presented.
