Abstract
We present the development of the light detectors with magnetic microcalorimeter (MMC) readouts designed for the AMoRE neutrinoless double beta decay experiment. The detectors are composed of Ge or Si wafer as an absorber for scintillation light and an MMC detector to monitor the temperature of the wafer. Five measurements were carried out with one Ge wafer and four Si wafers prepared under various conditions. Different details of the light detector assembly have been tested to find the optimal configuration for the future AMoRE-II experiment. Direct comparisons in signal size were performed with the different wafers while considering favorable conditions for the future AMoRE setup. Moreover, a baseline resolution of 34.3 eV FWHM was obtained in a detector setup with a 2-inch Si wafer.
