  The MAJORANA DEMONSTRATOR is sensitive to rare events near its energy
threshold, including bosonic dark matter, solar axions, and lightly ionizing
particles. In this analysis, a novel training set of low energy small-angle
Compton scatter events is used to determine the efficiency of pulse shape
analysis cuts, and we present updated bosonic dark matter and solar axion
results from an 11.17 kg-y dataset using a 5 keV analysis threshold.
