  Since the beginning of 2008 the DAΦNE complex started to test the "crabbed scheme" to improve the luminosity performance of the accelerator. In order to ensure a fast, accurate and absolute measurement of the luminosity and to fully understand the background conditions, the new interaction region has been equipped with three different luminosity monitors: a Bhabha calorimeter, a Bhabha GEM tracker and a gamma bremsstrahlung proportional counter. The detectors design, construction, and performance, as well as the first measurements performed at DAΦNE during the crab waist commissioning are here presented. Data are also compared with the Monte Carlo simulations of the full setup. First results acquired during the SIDDHARTA run are supposed to be presented.

  The new idea of increasing the luminosity of a collider with crabbed waist collisions and first experimental results from DAΦNE using this concept are presented. Consequences for the design of future factories will be discussed. An outlook to the performance reach with crabbed waist collisions is given, with emphasis on future B Factories.

  In the second half of 2007 a major upgrade has been implemented on the Frascati DAΦNE collider in order to test the novel idea of Crab Waist collisions. New vacuum chambers and permanent quadrupole magnets have been designed, fabricated and installed to realize the new configuration. At the same time the performances of relevant hardware components, such as fast injection kickers and shielded bellows have been improved relying on new design concepts. The collider has been successfully commissioned in this new configuration. The paper describes the new layout as well as several experimental results about linear and non-linear optics setup and optimization, damping of beam instabilities and discusses the obtained luminosity performances.

  The DAΦNE Beam Test Facility is in operation since the 2003 and has been continuously improved and upgraded in order to take into account the many different requests coming from the high energy and accelerator community. The facility was initially optimized to produce single electron and positron in the 25-750 MeV energy rage, manly for high energy detector calibration and testing; it can now provide beam in a wider range of intensity, up to 1010 electrons/pulse, typically needed for accelerator diagnostic tests. In the last two years the facility has also been modified in order to produce tagged photons, and the possibility to deliver tagged neutrons in the MeV energy range is under study. The main results obtained, the performance and the most significant characteristics of the facility diagnostics and operation are presented, as well as the users experience collected during these years of operation.
