Poster Neutrinoless double beta decay Poster


AXEL (A Xe ElectroLuminescence) is a project aiming to search for Neutrinoless Double Beta Decay ($0\nu \beta \beta$) of $\mathrm{^{136}Xe}$, using a high-pressure gas Xe time projection chamber. The performance was demonstrated with the 180L detector; energy resolution of 0.92%(FWHM) was achieved at 1836 keV. Currently, construction of a 1,000L detector is on going to start the $0\nu \beta \beta$ search. Expected sensitivity and the construction status will be reported.
