In 1967 Edwin McMillan proposed the first stable nonlinear accelerator focusing system (Report UCRL-17795). Since then, there have been several additional theoretical proposals on how to implement a practical nonlinear accelerator focusing system, but none were ever tested experimentally. This presentation will describe several practical proposals to implement nonlinear focusing elements in the Fermilab IOTA ring. These nonlinear elements would employ magnetic fields and electron lenses to create a large betatron tune spread and may help increase beam intensities in present and future accelerators, by providing space-charge compensation and increasing Landau damping.
