Multi-turn ERL mode of the S-DALINAC* — •Manuel Dutine, Michaela Arnold, Jonny Birkhan, Adrian Brauch, Jochim Enders, Marco Fischer, Ruben Grewe, Lars Juergensen, Maximilian Meier, Norbert Pietralla, Felix Schliessmann, Dominic Schneider, Merle Seeger, Alexander Smuskin, and Manuel Steinhorst — Institut für Kernphysik, Technische Universität Darmstadt

The superconducting Darmstadt linear accelerator S-DALINAC is a thrice-recirculating accelerator for electrons supporting a variety of experimental programs in nuclear physics and nuclear photonics. Besides the conventional acceleration scheme, it can also be operated as an energy-recovery linac (ERL) [1] and contributes to research on this exciting topic of technology development. The world-wide first successful operation as a superconducting multi-turn ERL has been demonstrated in August 2021 [2]. A variety of projects address further developments, for instance, dedicated diagnostics to measure the position of two beams in the same beamline, simultaneously, or to resolve its time structure, have been used for first measurements. This contribution gives an overview of their status. [1] M. Arnold et al., First operation of the superconducting Darmstadt linear electron accelerator as an energy recovery linac, Phys. Rev. Accel.
