  AFTER@LHC is an ambitious fixed-target project in order to address open
questions in the domain of proton and neutron spins, Quark Gluon Plasma and
high-$x$ physics, at the highest energy ever reached in the fixed-target mode.
Indeed, thanks to the highly energetic 7 TeV proton and 2.76 A.TeV lead LHC
beams, center-of-mass energies as large as $\sqrt{s_{NN}}$ = 115 GeV in pp/pA
and $\sqrt{s_{NN}}$ = 72 GeV in AA can be reached, corresponding to an
uncharted energy domain between SPS and RHIC. We report two main ways of
performing fixed-target collisions at the LHC, both allowing for the usage of
one of the existing LHC experiments. In these proceedings, after discussing the
projected luminosities considered for one year of data taking at the LHC, we
will present a selection of projections for light and heavy-flavour production.
