Higher instantaneous and daily integrated luminosity compared to previous runs.

Maintained background levels suitable for efficient data acquisition.

Abstract

After a long preparatory phase, including a wide hardware consolidation program, the Italian lepton collider DAFNE, is now systematically delivering data to the KLOE-2 experiment. In approximately 200 days of operation 1 fb-1 has been given to the detector limiting the background to a level compatible with an efficient data acquisition. Instantaneous and maximum daily integrated luminosity measured, so far, are considerably higher with respect to the previous KLOE runs, and are: L(inst) ~ 2.0 1032 cm-2s-1, and L(day) ~ 12.5 pb-1 respectively. A general review concerning refurbishing activities, machine optimization efforts and data taking performances is presented and discussed.
