Description

This talk will describe planned experiments to validate theoretical and computational models of space charge effects in the SNS Accumulator Ring (AR). I will discuss the potential to leverage the world-leading bunch intensity (2.25e14), flexible energy range (800-1300 MeV), four-dimensional phase space painting, and longitudinal bunch compression in the AR to push the tune shift to large values (greater than 0.5). I will also highlight the diagnostics available to image the phase space distribution during beam accumulation and storage. Together, these capabilities could advance our understanding of intense beams and provide valuable benchmarks for computer simulations.
