Abstract
This paper introduces a new platform established for nuclear astrophysics studies on Hefei Facility in China. Currently, the high-voltage accelerator can deliver a proton beam with current up to approximately 5 mA in the energy range of ∼50–350 keV. The proton beam energy and its spread were calibrated with two resonant reactions, and satisfy the experimental beam requirements for nuclear astrophysics studies. At the 90∘ beamline of this platform, we have installed a new setup (including target chamber, cold trap, silicon detectors, preamplifiers and DAQ), which is specifically designed for charged-particle measurements. Based on a careful background study of the target chamber, the charged-particle measurement of the 19F(p, α0)16O reaction can be performed down to the low-energy region of astrophysical interest with this setup. Some other astrophysical experiments are also prospected.
