Abstract

DAΦNE is the electron-positron collider operating at the energy of Φ-resonance, 1 GeV in the center of mass. The presently achieved luminosity is by about two orders of magnitude higher than that obtained at other colliders ever operated at this energy. Careful beam dynamic studies such as the vacuum chamber design with low beam coupling impedance, suppression of different kinds of beam instabilities, investigation of beam-beam interaction, optimization of the beam nonlinear motion have been the key ingredients that have helped to reach this impressive result. Many novel ideas in accelerator physics have been proposed and/or tested experimentally at DAΦNE for the first time. In this paper we discuss the advanced accelerator physics studies performed at DAΦNE.

In this paper we discuss the advanced accelerator physics studies performed at DAΦNE
Considering high efficiency of the scheme for increasing collision luminosity and its relative simplicity for implementation several new collider projects have been proposed and are under development at present. These are the SuperKEKB Bfactory already under commissioning in Japan [12], the SuperC-Tau factory proposed in Novosibirsk and entered in the short list of Russian mega-science projects [13], the new 100-km electron-positron Future Circular Collider (FCC-ee) under design study at CERN [14], the Higgs Factory CEPC in China [15] and some others

Summary

Introduction

DAΦNE is one of the seven charged particle colliders operating in the world. It is an electron-positron collider working at the energy of the Φ resonance (1.02 GeV c.m.) aimed at providing a high rate of K mesons production [1, 2]. The presently achieved luminosity is by about two orders of magnitude higher than that obtained at other colliders ever operated at this energy. The presently achieved peak luminosity of 4.5x1032 cm-2s-1 is by about two orders of magnitude higher than that obtained at other colliders ever operated at the same energy.
