A polarized fixed-target experiment at LHC will open the way for a broad and unique physics program. The kinematic coverage will allow to also study the negative-rapidity region in the CM, corresponding to the poorly explored high x-Bjorken domain for the target proton. Furthermore, the use of a polarized H or D gas will allow precision measurements of spin-asymmetries in Drell-Yan and in inclusive production of quarkonia, thus opening the way to the measurement of the unknown gluon PDFs, such as the gluon Sivers function. The idea of installing a gaseous polarized target into the LHCb detector is discussed.
