Abstract
Long-range beam-beam interactions (parasitic crossings) are one of the main luminosity performance limitations for the Frascati e+e- Phi-factory DAFNE. In particular, the parasitic crossings lead to a substantial lifetime reduction of both beams in collision. This puts a limit on the maximum storable current and, as a consequence, on the achievable peak and integrated luminosity. In order to alleviate the problem numerical and experimental studies of the parasitic crossings compensation with current-carrying wires have been performed at DAFNE. Two such wires have been installed at both ends of the KLOE interaction region. Switching on the wires in agreement with the numerical predictions, improvement in the lifetime of the 'weak' beam (positrons) has been obtained at the maximum current of the 'strong' one (electrons) without luminosity loss. In this paper we describe the parasitic crossings effects in DAFNE, summarize the results of numerical simulations on their compensation with the wires and discuss the experimental measurements and observations.
