APOLLON is a proposal to measure the polarization asymmetry of J/{psi} photoproduction in a fixed target experiment at HERA in an effort to provide information on the gluon spin distribution in the nucleon. Inelastic production will be identified via the {mu}{sup +}{mu}{sup -} decay channel, resulting in a statistical precision of {delta}A=0.05 in a 12 month run. In the LO CSM, the corresponding precision in {delta}G(x)/G(x) is 0.15 at x{approx}0.4.
