  Extraction of the multi-TeV proton and lead LHC beams with a bent crystal or
by using an internal gas target allows one to perform the most energetic
fixed-target experiment ever. pp, pd and pA collisions at $\sqrt{s}$ = 115 GeV
and Pbp and PbA collisions at $\sqrt{s_{\rm{NN}}}$ = 72 GeV can be studied with
high precision and modern detection techniques over a broad rapidity range.
Using the LHCb or the ALICE detector in a fixed-target mode offers
unprecedented possibilities to access heavy-flavour production in a new energy
domain, half way between the SPS and the nominal RHIC energy. In this
contribution, a review of projection studies for quarkonium and open charm and
beauty production with both detector set-ups used with various nuclear targets
and the LHC lead beams is presented.
