Physics:DAFNE
From HandWiki
DAFNE or DAΦNE (Double Annular Φ Factory for Nice Experiments), is an electron-positron collider at the INFN Frascati National Laboratory in Frascati, Italy.[1][2] It consists of 2 accelerator rings, both approximately 100 meters in length. Since 1999 it has been colliding electrons and positrons at a center of mass energy of 1.02 GeV to create phi mesons (φ). 85% of these decay into kaons (K), whose physics is the subject of most of the experiments at DAFNE.
There have been five experiments at DAFNE:
- KLOE (K LOng Experiment), led by Juliet Lee-Franzini[3], which studied CP violation in kaon decays and rare kaon decays from 2000 to 2006[4]. This experiment was followed by the KLOE-2 experiment.
- FINUDA (FIsica NUcleare a DAFNE), studies the spectra and nonmesonic decays of hypernuclei containing lambda baryons (Λ). The hypernuclei are produced by negatively charged kaons (K−) striking a thin target.
- DEAR (DAFNE Exotic Atoms Research experiment), determines scattering lengths in atoms made from a kaon and a proton or deuteron.
- DAFNE Light Laboratory (DAΦNE-L) consists of 3 lines of synchrotron radiation emitted by DAFNE, a fourth is under construction.
- SIDDHARTA (SIlicon Drift Detectors for Hadronic Atom Research by Timing Application), aims to improve the precision measurements of X-ray transitions in kaon atoms studied at DEAR.
