Construction and beam commissioning of a compact proton synchrotron for space radiation environment simulation

The Xi’an Proton Application Facility (XiPAF) is dedicated to simulations of environments containing space radiation. The facility consists of a 7 MeV linac injector followed by a compact 200 MeV synchrotron. The project was officially launched in 2014. After six years of construction, the commissioning of the synchrotron began in early 2020. Several rounds of beam commissioning have yielded an extracted beam energy from 10 to 200 MeV, with the number of protons exceeding 5 × 1010 in each cycle at different energies. This study presents the latest results from beam commissioning at XiPAF.
