Abstract

Calcium fluoride for the study of Neutrinos and Dark matters by Low-energy Spectrometer (CANDLES) searches for neutrino-less double-beta decay of Ca-48 using a CaF2 scintillator array. A high Q-value of Ca-48 at 4268 keV enabled us to achieve low background, however, at the same time it causes difficulties in calibrating the detector's Q-value region because of the absence of a standard high-energy gamma-ray source. Therefore, we have developed a novel calibration system based on gamma-ray emission by neutron capture on Si-28, Fe-56, and Ni-58 nuclei. In this paper, we report the development of the new calibration system as well as the results of energy calibration in CANDLES up to 9 MeV.
