Abstract :
Starting with the third (1992) run, closed orbits of protons and antiprotons will be helically separated everywhere in the Tevatron except at interaction regions B0 and D0. Helical separation makes it possible to improve the initial luminosity greatly, but also brings the problem of long-range beam-beam interactions. What is the contribution of long-range interactions to beam lifetime, to emittance growth, and to background noise in the detectors? How much separation will be sufficient? What are the scaling laws relevant to long-range interactions? The authors address these questions.<>
