Description

We have begun 2.5 MeV proton operations at the Integrable Optics Test Accelerator (IOTA) in Fermilab to study beam dynamics with an incoherent tune shift approaching 0.5 in a zero‑wakefield environment. We present a detailed comparison of predicted dynamics in bare IOTA (dipoles and quadrupoles only) from several simulation codes, including ImpactX, Lifetrac, MAD-X, PyORBIT, and Xsuite. We compare these simulations with experimental results from coasting‑beam operations in IOTA and discuss next steps.
