2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/86024The design of an Interaction Region (IR) suitable to reach low values of the beta functions at the Interaction Point (IP) and a high collision frequency is a rather difficult task in a short ring as DAPHNE, where an upgrade of the peak luminosity to 10^34 cm-2s-1 is aimed [1]. In the following, general considerations on the design of such an IR are presented, together with a preliminary design; the final design will however be the result of a joint collaboration between accelerator and detector physicists.Invited talk at the Workshop on e+e- in the 1-2 GeV range, Alghero, Italy, September 2003 (eConf C0309101)Accelerator Physicstext
