The Integrable Optics Test Accelerator (IOTA) at the Fermilab Accelerator Science and Technology (FAST) facility has been operating since 2018. The IOTA ring was first commissioned with 100-MeV electrons and, to date, performed two experimental runs. The primary goal of these two runs was to study beam dynamics in the integrable and near-integrable focusing configurations with special non-linear magnets and with profiled octupoles. The flexibility of the IOTA ring allowed it to cover a wide range of complimentary studies, such as experiments with a single electron, studies of undulator radiation and to test IOTA with low emittance beams.
At present, the IOTA Run-3 physics program is focused on Optical Stochastic Cooling and in the near future, a proton injector will be constructed and commissioned. This would complete a premier accelerator physics test facility with lasers, linacs, a ring, and with photons, electrons, and protons. This talk will describe the accelerator science program at IOTA and will highlight the emerging collaboration opportunities.
