  The Deep Underground Neutrino Experiment (DUNE) provides a rich science
program with a focus on neutrino oscillations and other beyond the standard
model physics. The high-intensity, wide-band neutrino beam will be produced at
the Fermi National Accelerator Laboratory (FNAL) and will be directed to the
40~kt liquid argon far detector at the Sanford Underground Research Facility,
1300~km from FNAL. The primary goals of the experiment are to determine the
ordering of neutrino masses and to measure the CP violating phase,
$\delta_{\textrm{CP}}$. The underground location of the large DUNE far detector
and its excellent energy and spatial resolution will allow also for
non-accelerator physics programs predicted by grand unified theories, such as
nucleon decay or $n$---$\bar{n}$ oscillations. Moreover, DUNE will be sensitive
to the electron neutrino flux from a core-collapse supernova, providing
valuable information on the phenomenon's underlying mechanisms. This ambitious
project requires extensive prototyping and a testing program to guarantee that
all parts of the technology are fully understood and well tested. Two such
prototypes, in both single phase (ProtoDUNE-SP) and dual phase (ProtoDUNE-DP)
technologies, are under construction and will be operated at the CERN Neutrino
Platform (NP) starting in 2018.
