A Study of Time Dependent Noise in the \textsc{Majorana Demonstrator} Waveforms
POSTER
Abstract
The \textsc{Majorana Demonstrator} is an array of high purity germanium detectors searching for neutrinoless double-beta decay in $^{76}$Ge and performing searches for beyond standard model (BSM) physics. The BSM searches are possible because of the \textsc{Demonstrator}'s low trigger threshold, below 1 keV. Such low thresholds can be sensitive to changing noise conditions. Understanding the nature of this noise is critical to our ability to perform BSM searches. An analysis of the RMS of waveform baselines in \textsc{Demonstrator} data helps provide better understanding of the electronic noise conditions present in the experiment so that potential issues can be identified and resolved. I present a comparison of the baseline RMS distributions in individual detectors before and after changes in noise, including an investigation of how changing noise conditions are correlated between different detectors.
