  Intense and collimated neutrino beams are produced by charm and beauty
particle decays from proton-proton collisions at the LHC. A neutrino experiment
would be run parasitically without interrupting the LHC physics program during
the collider run. We estimate the neutrino fluxes from proton-proton collisions
at $\sqrt{s}=14$ TeV of the LHC with the designed luminosity, $10^{34} \lumi$.
By mounting about 200 tons of fiducial volume of a neutrino detector at 300
$\m$ away from the interaction point, about 150,000 of charged current neutrino
events per year can be observable.
