[en] The operation of DAFNE, the 1.02 GeV c.m. e⁺e^- collider of the Frascati National Laboratory with the KLOE experimental detector was successfully concluded in March 2006. Since April 2004 it delivered a luminosity > 2 fb^-1 on the peak of the Φ resonance, > 0.25 fb^-1 off peak and a high statistics scan of the resonance. The best peak luminosity obtained during this run was 1.5 10³² cm^-2s^-1, while the maximum daily integrated luminosity was 10 pb^-1. The KLOE detector has been removed from one of the two interaction regions and its low beta section substituted with a standard magnetic structure allowing for an easy vertical separation of the beams, while the FINUDA detector has been moved onto the second interaction point. Several improvements on the rings have also been implemented and are described together with the results of machine studies aimed at improving the collider efficiency and testing new operating conditions
