Description
The CDEX-300 is a next generation neutrinoless double beta (0$\nu\beta\beta$) decay experiment based in China Jinping underground laboratory (CJPL). CDEX-300 aims at searching the 0$\nu\beta\beta$ decay of Ge-76 in the inverted neutrino mass hierarchy using high purity germanium (HPGe) detectors. We propose to build a 200 kg HPGe array with 2.5 keV (FWHM) energy resolution and 1E-4 cts/keV/kg/yr background level in the 2039 keV signal region. CDEX-300 is projected to achieve a $1.92\times10^{27}$ yr Ge-76 0$\nu\beta\beta$ half-life 3$\sigma$ discovery sensitivity with a 10-yr operation. This report will outline the experimental design, background control technologies, and the physical potential of the CDEX-300.
