A Multidirectional Magnetic Holding Coil for ELSA — •Victroia Lagerquist and Hartmut Dutz for the CBELSA/TAPS collaboration — University of Bonn

The current physics program at ELSA includes the ability to measure either transverse or longitudinal polarization observables through the use of dedicated, single purpose, internal magnetic holding coils. However, the process of changing between these coils requires significant effort and extensive downtime. We propose a single, combined, multi-directional coil which enables polarization at an arbitrary angle without the need for a physical configuration change. This combined coil has been optimized to a comparable efficiency and material budget as each of the original individual coils. I will present the current status of this ongoing project.
