The Scraper System at S-DALINAC and ERL application — •M. Fischer, M. Arnold, M. Dutine, L. Jürgensen, N. Pietralla, F. Schließmann, and D. Schneider — Institute for Nuclear Physics, Technische Universität Darmstadt, Germany

Scraper systems in particle accelerators are utilized for safely and efficiently removing undesired particles from the beam, e.g., those with too large momentum deviation or those belonging to the beam halo. They are of great importance for accelerators, in particular those with high energies and beam currents, where the risk of damage is high. In addition to the machine protection, the use of scraper systems can significantly improve the beam quality and reduce the experimental background. Also, such systems can be used for online beam diagnostics. Especially when operating an Energy Recovery Linac (ERL), it is important to prepare the beam for the return to the accelerator after the interaction with an experiment. In this contribution, we will present results of recent measurements with the High-Energy Scraper System of the S-DALINAC [1] and give an overview on the ongoing work. This work was supported by the state of Hesse within the cluster project ELEMENTS and within the LOEWE research project Nuclear Photonics
