Hamiltonian perturbation theory and simulations with Synergia, Warp and other codes are being used to develop an experimental program for beam dynamics, including the highly nonlinear 'elliptic' magnet originally proposed by Danilov and Nagaitsev. The results suggest a number of experiments that could be performed at IOTA. For example, small changes in the linear tune and the strength of the elliptic magnet can be used to control dynamic aperture. Both electron and proton beams can be used to measure the tune spread as a function of the elliptic magnet strength, for comparison with theory. Space charge driven halo formation due to envelope oscillations can be measured over a range of elliptic magnet strengths. Theoretical and computational results will be presented to guide future decisions regarding experimental diagnostics for IOTA. PB - JACoW CP - Geneva, Switzerland ER -
