We report on the results of a survey to discover X-ray emission from powerful radio jets. Our objectives included initial correlations to the radio and optical jet emission to elucidate the predominant emission mechanism, and to find objects of interest for follow-up Chandra studies. With X-ray data in hand for all 56 survey objects, we detect about 60% in our 5 to 10 ks Chandra observations. We use these to explore the predicted (1+z)4 dependence of the ratio of X-ray to radio flux density, as expected if the X-rays arise from inverse Compton (IC) scattering on the cosmic microwave background (CMB). Assuming the IC/CMB emission mechanism, we examine the distribution of magnetic fields, bulk Lorentz factors, angles to the line of sight, and kinetic energy flux carried by these 100 kpc long jets.From longer followup observations, we resolve the structure of magnetic fields and kinetic energy flux along the jet. This research was supported by NASA contract NAS8-03060 and SAO Grant GO9-0121B .
