Arc design and simulations for the ERL-facility concept DICE — •Fatemeh Sadat Moujani Ghomi, Michaela Arnold, Lars Jürgensen, Norbert Pietralla, and Felix Schliessmann — Institut für Kernphysik, Technische Universität Darmstadt, Darmstadt, Germany

This contribution focuses on the design of an arc section for the ERL-concept study Darmstadt Individually recirculating Compact Energy recovery linac (DICE). The arc section consists of two vertical dog-legs and a total horizontal bend of 180^∘. Correspondingly, dispersion terms of both transverse planes must be controlled and, additionally, values for the longitudinal dispersion must be set depending on the operating mode. Here, the tracking software ELEGANT and its implemented optimization algorithms are used to find a suitable arc design and a proper behavior for the dispersion terms and beam envelopes. The overall goal is a compact design that can ideally be adapted for all arcs of DICE. We will discuss the parameters for a variable design of the arc sections of DICE and their justifications.
