The design and performance of the luminosity monitor for Fermilab experiment E760, in which the circulating antiproton beam in the FNAL antiproton accumulator intersects a hydrogen gas-jet target, is described. Absolute luminosity monitoring at the level of ±0.8% (statistical) ±2.1% (systematic) is achieved. The luminosity monitor also enables forward scattering parameters to be measured for momenta in the 3-8 GeV range with greater precision than achieved before.
