  SND@LHC is a compact experiment that will detect high energy neutrinos
produced by heavy flavour quarks at the LHC in the pseudo-rapidity region 7.2
$< \eta <$ 8.6. It is an hybrid system, comprising nuclear emulsions and
electronic detectors, that allows all three $\nu$ flavours to be distinguished,
thus opening an unique opportunity to probe the physics of charm production in
the very forward region. The first phase aims at operating the detector
throughout LHC Run 3 collecting a total of 150 fb$^{-1}$. The electronic
subdetectors were assembled in the summer and recently operated in test beams.
