The experiment is a precision measurement of Drell-Yan yields from hydrogen and deuterium. The ratio of these yields can be used to infer the ratio ubar(x)/dbar(x) in the proton, over the x interval between 0.03 and 0.3. Measures also the J/psi, psi', Upsilon, Upsilon', and Upsilon'' yields from both targets. Uses the Magnetic Dilepton Spectrometer, with 3 dipoles, 3 stations of wire chambers, 1 station with prop-tubes, 4 hodoscope stations, and high rate capability with better than 100 MeV resolution at the J/psi. Beam produces 10**(12) protons/spill. Targets are LH and LD. Targets for the J/psi studies were Be, Fe and W
