Description
The High-Intensity heavy-ion Accelerator Facility (HIAF) is a proton and ion accelerator facility, coupling a superconducting linac (iLinac) with a synchrotron to produce intense stable and radioactive beams with energies ranging from MeV/u to GeV/u. The official construction began on December 23, 2018, with the entire beam commissioning phase launched on October 27, 2025. Within 30 hours, the 18O6+ beam was accumulated, accelerated to 2.6 GeV/u with a fast ramping rate of 12 T/s inside the BRing, and then transferred and stored in the SRing successfully. Following a month of iLinac optimization, two high-intensity beams were then commissioned and tested in December: 18O6+ at 2.6 GeV/u with 2.5E11 particles per pulse (ppp) extracted from BRing and 209Bi31+ at 851 MeV/u exceeding 3.0E10 ppp. Those results confirms that the facility’s performance has surpassed its design specifications. The day-one experiment was started by the end of 2025. A diverse suite of instrumentation systems played a crucial role during the extremely fast beam commissioning, enabled the matching of different accelerator sections with high transmission rates, helped to achieve efficient acceleration and high intensity with low beam loss. In this paper, we present the initial beam measurements, as well as lessons learned from the experience.
