  The DAPHNE Phi-Factory upgrade, foreseen for the Siddharta detector run in 2007, will require a new magnetic and mechanical layout to exploit the "large crossing angle" and "crabbed waist" concepts*. New permanent quadrupole magnets and aluminium vacuum chamber with thin window have been designed for the new interaction region, with the aim to reuse at maximum the present magnetic and vacuum chamber components. A vacuum chamber of novel design will allow separating the beams at the second interaction region. Designs and results for the new layout will be presented.

  Beam operations on DAΦNE restarted on October 2006 after a four months shut-down to remove the KLOE experimental detector and to install the FINUDA one. This period has been also used for maintenance and implementation of several upgrades. In the first two months of operation the peak and integrated luminosity already exceeds the values obtained during the first FINUDA run by 20%. The DAΦNE goal is to deliver 1 fb-1 integrated luminosity by the end of May 2007. The collider performances during the run are presented together with the improvements obtained in terms of ring nonlinearities and beam dynamics coming from several collider modifications.
