Abstract

China JinPing underground Laboratory (CJPL) was established from a constructing hydro-power plants in the Jinping mountain, Sichuan, China. The facility is shielded by 2400 m of mainly marble overburden, with radioactively quiet rock, which is an ideal environment for nuclear astrophysics study with low cross section at the astrophysical relevant energy regions (Gamow window). A high current accelerator based on ECR source will finish the construction in 2018 for nuclear astrophysics experiment. The accelerator can provide beam energy from 0.05-0.4 MeV with beam current 12 mA proton beam and 6 mA He+ beam. In the first phase, several reactions of high astrophysical interest, like 12C(α,γ)¹⁶O "the holy grail" in nuclear astrophysics, ¹³C(α,γ)¹⁶O the key neutron source for the stellar s-process nucleosynthesis, ¹⁴N(p,γ)¹⁵O the slowest process in the CNO cycle, will be studied for the first within or near Gamow window.
