  The discovery of the Higgs boson has fully confirmed the Standard Model of
particles and fields. Nevertheless, there are still fundamental phenomena, like
the existence of dark matter and the baryon asymmetry of the Universe, which
deserve an explanation that could come from the discovery of new particles. The
SHiP experiment at CERN meant to search for very weakly coupled particles in
the few GeV mass domain has been recently proposed. The existence of such
particles, foreseen in Beyond Standard Models, is largely unexplored. A beam
dump facility using high intensity 400 GeV protons is a copious source of such
unknown particles in the GeV mass range. The beam dump is also a copious source
of neutrinos and in particular it is an ideal source of tau neutrinos, the less
known particle in the Standard Model. We report the physics potential of such
an experiment and describe the use of the RPC technology therein. An anchillary
measurement of the charm cross-section will be carried out in July 2018 and RPC
are used as a muon detector. We also describe the design and construction of
these new chambers.
