Some Aspects of the Two Beam Performance of DCI.

Front Cover
Lawrence Berkeley National Laboratory, 1991 - 27 pages
The results of beam-beam simulations that model DCI operating as an ee− collider are reported. The simulation techniques, including a new procedure for incorporating synchrotron radiation, are described. Phase advance errors between the interaction points explain the beam-beam limit at the operating point q(subscript x) = q{sub y} = 0.725 (q denotes the fractional part of the tune). The effects of radiation damping are also studied near that operating point. Simulation and experiments disagree in a second operating region, q(subscript x) = q{sub y} (almost equal to) 0.795, indicating additional physics outside the scope of our model.
