What about the short range future ? WE ARE THINKING ABOUT the possible DAFNE UPGRADE in luminosity AND energy To do what? 1)To complete the Kaon physics program 2)To measure the P, N,  time like form factors 3)To measure  interactions below 2.4 GeV 4)To measure the total cross section 5)To continue the systematic studies of exotic heavy and light nuclei 6)To have the most advanced accelerator technology 7)To have an even more intense Synchrotron light source

Why wigglers are important? To achieve the short damping times and ultra-low beam emittances needed in LC Damping Rings To increase the wavelength and/or brightness of emitted radiation in synchrotron light sources To increase radiation damping and control emittance in colliders E.
