  Null results for WIMP dark matter have led to increased interest in exploring
other dark matter candidates, such as Axions and Axion-Like Particles (ALPs),
which also helps in answering the strong CP problem. This experiment achieved a
sub-100 DRU (differential-rate-unit, expressed in counts/keV/kg/day) background
in the MeV region of interest by employing a combination of active and passive
veto techniques. Such a low background facilitates the search for ALPs with
axion-photon coupling $g_{a\gamma \gamma} > 10^{-6}$ and axion-electron
coupling $10^{-8}< g_{aee} < 10^{-4}$ in the 1 keV to 10 MeV mass range. This
indicates that the experiment has the capability to constrain the unexplored
cosmological triangle in the ALP-photon parameter space for ALPs in the MeV
mass range.
