Abstract

We propose a set of polarised-beam polarised target experiments to determine the complete set of spin dependent parton densities. The polarised valence quark densities are determined through semi-inclusive hadro-production in polarised muon-proton collisions. This, together with present data then fixes the polarised sea quark densities. Polarised gluon densities are measurable through asymmetries in large,pT direct photon production in polarised p-p collisions. An independent measurement of polarised sea quark densities comes from direct double photon production in polarised p-p collisions at rapidities close to zero. We illustrate these results with numerical estimates.
