Abstract: The neutrino oscillation needs parameters to be
measured precisely to provide essential information for a
modification of the Standard Model. Accomplishing this
novel goal in future neutrino experiments, such as the Deep
Underground Neutrino Experiment (DUNE) at Fermilab,
requires high flux neutrino beams and powerful
combination of near and far detectors. The Long Baseline
Neutrino Facility (LBNF) is under construction to provide
high intensity proton beams fed by the new PIP-II high
intensity LINAC and therefore high flux neutrino beams to
the experiment and the near and far detector sites, while the
DUNE collaboration is working on finalizing the design and
prototyping its detectors. This powerful facility being
prepared for the oscillation measurements makes it possible
to access physics Beyond the Standard Model, which was
inconceivable at a neutrino experiment in the past. In this
talk, I will discuss DUNE experiment itself, its beams and
detectors and discuss the prospects of searching for dark
matter and dark sector particles, along with their sensitivity
reaches. In addition, the new conceptual experiment, called
DAMSA that searches for DSP’s using the high intensity PIP-
II LINAC and its expected sensitivity reach will be discussed.
