Fermilab Circulates First Proton Beams in IOTA

US researchers at Fermilab announced they accelerated and stored the first proton beams in the FAST/IOTA test accelerator, achieving circulation at roughly 7% of light speed. The experiment uses a new low-voltage proton injector with a radio-frequency-quadrupole accelerator to deliver high-intensity beams for R&D on beam stabilization, AI-driven control and support for projects like PIP-II and the Deep Underground Neutrino Experiment.
