Abstract :
Beginning with the Fokker-Planck equation we present a new analysis of intrabeam scattering (IBS) in electron storage rings. Our approach is distinguished by having no ill-defined Coulomb logarithm, a fundamental drawback of previous approaches. We treat the case of linear xβyβ coupling in detail, deriving explicit expressions for the second moment invariants and their time evolution in the presence of IBS. We compare our results with those of Bjorken-Mtingwa, as well as with measurements performed at KEK´s ATF damping ring. More details of our derivations will be published elsewhere.
