were compared in the simulations, with the GuineaPig code**, in order to optimize both luminosity performances
and beam blow-up after collision. With such approach, luminosities of the order of 10 36 /(cm 2 sec) can be achieved.

DAFNE Status Report
The operation of DAFNE, the 1.02 GeV c.m.
e + e − collider of the Frascati National Laboratory
with the KLOE detector, started in
April 2004 has been concluded at the end of
March 2006 with a total delivered luminosity
of 2 fb-1 on the peak of the Phi resonance,
0.2 fb-1 off peak and a high statistics scan
of the resonance. The best performances of
the collider during this run have been a peak
luminosity of 1.5 1032 cm-2s-1 and a daily
delivered luminosity of 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.
Preliminary Study of a Crab Crossing System for DAFNE
The implementation of a crab crossing
scheme at the Frascati Phi-factory DAFNE
is under consideration, together with several
other ideas and upgrades to increase the col-

lider luminosity. The crab crossing is beneficial to the luminosity because it is expected to optimize the geometrical
superposition of the colliding bunches and to weaken the synchro-betatron beam-beam resonances. The basic specifications
of such a system, the expected luminosity increase, a preliminary design of the crab cavities and the
architecture of the dedicated RF system are presented.
