Exploring space charge mitigation with eigenpainting at the SNS

The Spallation Neutron Source uses charge exchange injection of 1.3 GeV, H- ions to accumulate roughly 2x10E protons per pulse in the accumulator ring. This is achieved using a flexible painting system capable of controlling all four transverse coordinates of injected beam over the 1ms injection cycle. Recently we demonstrated injection of an ~800 MeV beam into a single non-planar mode in the SNS ring, which we call eigenpainting. This poster will outline future plans for exploring the space charge dynamics of beams prepared by eigenpainting in the SNS ring, including comparison of hollow, gaussian, and uniformly painted beams.
