Let W be a Coxeter group and let Gw be the associated Artin group. We consider the local system over k(Gw, 1) with coefficients in R = Z[q, q-l] which associates to the standard generators of Gw the multiplication by q. For the all list of finite irreducible Coxeter groups we calculate the top-cohom
