Recent Developments at S-DALINAC* — •Michaela Arnold, Adrian Brauch, Manuel Dutine, Joachim Enders, Ruben Grewe, Lars Jürgensen, Maximilian Meier, Fatemeh Sadat Moujani Ghomi, Norbert Pietralla, Felix Schließmann, Dominic Schneider, and Alexander Smushkin — Institut für Kernphysik, Technische Universität Darmstadt, Darmstadt, Germany

The superconducting Darmstadt linear accelerator S-DALINAC is a thrice-recirculating accelerator for electrons. Besides the conventional acceleration scheme with corresponding nuclear physics experiments, the accelerator can also be operated as an energy recovery linac (ERL) [1]. Since its establishment in 1991, the S-DALINAC was mainly developed and operated by students. The latest achievement was the successful operation as a superconducting multi-turn ERL [2]. Dedicated diagnostics to measure both beams in the same beamline simultaneously are under commissioning. A streak camera will be used to optimize the bunch length. The operation is supported by machine learning techniques. A laser Compton backscattering setup is close to its commissioning. Other projects are working on further improvements of the machine. This contribution will give a complete overview.
