  LHCspin aims to upgrade the recently installed unpolarized gas target (SMOG2)
in front of the LHCb spectrometer to a polarised one. This task requires, in
the next few years, innovative solutions and cutting-edge technologies, and
will allow the exploration of a unique kinematic regime and new reaction
processes. With the instrumentation of the proposed target system, LHCb will
become the first experiment delivering simultaneously unpolarized beam-beam at
$\sqrt{s}$ = 14 TeV, and unpolarized and polarized beam-target collisions at
$\sqrt{s_{NN}}~\sim$ 100 GeV. LHCspin could open new physics frontiers
exploiting the potential of the most powerful collider and one of the most
advanced detectors.
