Description
Cryogenic detectors are widely used in searches for rare physics processes such as neutrino and dark matter interactions. Lowering the detection energy threshold not only helps better understanding of background but also enriches the physics program of the experiment. A new trigger method has been developed using Pearson correlation coefficient, also known as $r$-value. The new method compares the shape of the data with the signal template for trigger decision. It outperforms the conventional pulse height trigger in aspects of noise suppression, energy threshold, and trigger efficiency.
