Progress of Underground Nuclear Astrophysics Experiment JUNA in China

Abstract

Underground Nuclear Astrophysics Experiment in China (JUNA) will take the advantage of the ultra-low background in Jinping underground lab. A 400 kV high current accelerator with an ECR source and $\gamma$, neutron and charged particle detectors will be set up. A number of nuclear reactions important to hydrostatic stellar evolution near their Gamow window energies, such as $^{25}$Mg(p,$\gamma$)$^{26}$Al, $^{19}$F(p,$\alpha$)$^{16}$O, $^{13}$C($\alpha$,n)$^{16}$O and $^{12}$C($\alpha$,$\gamma$)$^{16}$O will be directly measured.
