DAΦNE upgrade: a new magnetic and mechanical layout

The DAΦNE Phi-factory upgrade, foreseen for the SIDDHARTA detector run in 2007, requires a new magnetic and mechanical layout to exploit the "large Piwinski angle" and "crab waist" concepts [1]. New permanent quadrupole magnets and aluminium vacuum chamber with thin window have been designed for the new interaction region, with the aim to reuse as far as possible the present magnetic and vacuum chamber components. A vacuum chamber of novel design will allow separating the beams at the second interaction region. The new layout together the new hardware components are presented.
