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 program2) To measure the P, N, time like form factors3) To measure interactions below 2.4 GeV4) To measure the total cross section5) To continue the systematic studies of exotic heavy

and light nuclei6) To have the most advanced accelerator technology 7) To have an even more intense Synchrotron light

source

Higher frequencies – lower acceptanceLower frequencies – higher voltage

R&D on SC cavities with SRFF experiment in DAFNE

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. Levichev

We can make use of the recent progress in SUPERCONDUCTING wiggler technology

Operating experiences:CESRc, ELETTRA, CAMD

R&D in progress:ILC, ATF, PETRA3, …
