We report the development of a CaMoO4 crystal low temperature detector for the AMoRE neutrinoless double beta decay search experiment. The prototype detector cell was composed of a 216 g CaMoO4 crystal and a metallic magnetic calorimeter. An overground measurement demonstrated FWHM resolution of 6–11 keV for full absorption gamma peaks. Pulse shape discrimination was clearly demonstrated in the phonon signals, and 7.6  of discrimination power was found for the and separation. The phonon signals…
