EXPERIMENTAL STUDIES OF NONLINEAR INTEGRABLE OPTICS
This talk presents experimental studies of a novel accelerator lattice design concept, the nonlinear integrable optics (NIO), aimed at enhancing beam stability limits with little to no beam dynamics degradation. Tests with two NIO devices, the quasi-integrable octupole system and the fully integrable Danilov-Nagaitsev system, were carried out at the purpose-built Integrable Optics Test Accelerator (IOTA) at Fermilab. Their simulation, hardware design, and commissioning process is presented. Extensive model and analysis algorithm development and benchmarking is described. Electron beam measurements from two scientific runs are analyzed, yielding frequency and phase space dynamics consistent with models. These results demonstrate viability and advantages of the NIO design, providing the groundwork for proton studies in the strong space-charge regime and future state-of-the-art integrable accelerators.
