Abstract
We present a systematic trigger study for the Advanced Molybdenum-based Rare process Experiment (AMoRE), an international project searching for the neutrinoless double beta decay (\(0\nu \beta \beta \)) of \(^{100}\hbox {Mo}\). AMoRE utilizes a heat and light detection method at millikelvin temperatures. A detector module of AMoRE is composed of a large crystal absorber and metallic magnetic calorimeter temperature sensors. We applied a software filter with various conditions to the continuously saved data from the current AMoRE setup. With a trigger level set to 5 times the standard deviation of the noise signals resulting from a Butterworth filter, an energy threshold, defined as the energy of the signals leading to a 50% trigger efficiency, was found to be 2.2 keV.
