Optics design and space charge effects in Injection arc of MESA* — •Aamna Khan1, Oliver Boine-Frankenheim1, and Christian Stoll2 — 1Institut für Theorie Elektromagnetischer Felder, TU Darmstadt, Darmstadt-64289, Germany — 2Institut für Kernphysik, Johannes Gutenberg-Universitat, D-55099 Mainz, Germany.
For intense electron bunches traversing through bends, as for example the recirculation arcs of an ERL, space charge (SC) may result in beam phase space deterioration. SC modifies the electron transverse dynamics in dispersive regions along the beam line and causes emittance growth for mismatched beams or for specific phase advances. The study focuses on the optics design, including SC, of a 180° low energy (5 MeV) injection arc which is matched to the injector with first cryomodule for energy recovery operation in the Mainz Energy-recovering Superconducting Accelerator (MESA). MESA should deliver a CW beam at 105 MeV for physics experiments with an internal target.
