Title: Limitations Imposed by Beam-Beam Effects and Their Remedies

Abstract

Effects that limit the luminosities of a general purpose linear collider or GLC capable of spin polarized e{sup {+-}}e{sup {+-}}, gamma-e{sup {+-}} and spin polarized gamma-gamma incident channels are discussed together with potential mitigations. The relative characteristics of such channels and their luminosities are predicted based on differing assumptions - including those for the current configurations for the NLC at square root s{sub ee} = 0.5 and 1.0 TeV. Disadvantages related to the increased complexity of linear colliders can be offset by broader design constraints that seek to optimize the generalized luminosity. Decreased disruptions and bunch charges are effective and can be used in combination with feasible charge compensation schemes to predict higher luminosities and power conversion efficiencies. The incremental costs of additional channels is modest compared to the cost of any one by itself or potential gains in the integrated luminosity.
