Experiment is using 160 GeV beam of polarized muons and longitudinaly polarized deuterium in a 6LiD double-cell target. The gluon polarization, Δg/g, is determined from the double-spin cross section asymmetries for the events selected by tagging the photon-gluon fusion process. Two methods of tagging are used: by requiring or in the final state and by having two hadrons of large pt. We obtain three independent preliminary results on Δg/g at ηg ≈ 0.12: (1) from open charm production, (2) from large pt hadrons using events with Q2 > 1GeV2 and (3) from large pt hadrons with Q2 < 1GeV2. Prospects to improve the accuracy of Δg/g will be given.
