Beam Dynamics for a High Current 3 MeV, 325 MHz Ladder-RFQ — •Marc Syha, Maximilian Schütt, Marcus Obermayer, and Ulrich Ratzinger — Institut für Angewandte Physik, Goethe- Universität Frankfurt, Max-von-Laue-Str. 1, 60438 Frankfurt am Main

After the successful measurements with a 0.8 m prototype a 3.3 m Ladder-RFQ is under construction at IAP, Goethe University Frankfurt. It is designed to accelerate protons from 95 keV to 3.0 MeV according to the design parameters of the p-linac at FAIR.

The development of an adequate beam dynamics was done in close collaboration with the IAP resonator design team. The Los Alamos RFQGen-code was used for the beam simulations. A constant vane curvature radius and at the same time a flat voltage distribution along the RFQ was reached by implantation of the modulated vane geometry into MWS-CST RF field simulations.

Point of reference for the beam dynamics layout are the beam dynamics designs of C. Zhang* and A. M. Lombardi**. This poster presents the simulation results with the main vane modulation parameters.
