A Status Report of KLOE at DAFNE

High Energy Physics - Experiment 2009-10-31 v1

Abstract

The major goal of the KLOE experiment is to measure Re(epsilon' /epsilon) in the kkbar system, with a precision of 10^{-4},both via the traditional double ratio method and quantum interferometry. The experiment has started taking data at DAFNE, the phi-factory built at the Frascati National Laboratory (LNF) of INFN in Italy, beginning in April 1999. In the early phase of the commissioning (before KLOE roll-in), DAFNE has achieved multi bunch luminosities of 10^{31} cm^{-2} s^{-1} with 13 bunches and 200 mA. Detailed studies are presently underway to compensate for the large perturbation brought in by the KLOE solenoid, which has caused a drastic decrease of the peak luminosity. Nevertheless the first collected data, corresponding to an integral luminosity of 220 nb^{-1}, show that KLOE is performing to the design specifications in all its hardware and software components.
