Experience with DAFNE Upgrade Including Crab Waist

In 2007 DA NE was upgraded to operate in a regime of large Piwinski angle, with a novel interaction region optics, reduced vertical beta at the interaction point, and additional sextupoles providing for Crab-Waist collisions. The specific luminosity has been boosted by more than a factor of four at low currents, and the present peak luminosity is by about a factor of 3 higher than the maximum value obtained with the original collider configuration. The DA NE commissioning as well as the first experience with large Piwinski angle and Crab-Waist collisions scheme will be reported.
