e+e− Collider with Monochromatization and Maximum Beam Energy of ~200-300 MeV for True Muonium Production and Other Experiments | |
|
||
| We present preliminary description of compact e+e− collider with maximum beam energy of 300 MeV. At the beam energy of 100 MeV the physics program includes first production, observation and study of true muonium (bound state of mu+mu-). The width of true muonium is very narrow; therefore, we implemented monochromatization scheme proposed by A. Reniere. At higher energy, goals are to measure pion form factor and cross sections of rare decays. The small size and energy of the collider simplify design of the magnets, vacuum chamber, RF system and radiation protection decreasing construction time and cost of the whole facility. The accelerator is interesting from accelerator point of view because of monochromatization, beam-beam effects with dispersion, intra-beam scattering study and suppression. | ||

Review of Interaction Regions for Crab Waist Colliders | |
|
||
| Invention of the crab waist collision scheme gave birth to several projects of future colliders with luminosity by one or two orders of magnitude higher than in previous particle factories. The biggest influence in luminosity gain comes from extremely small vertical beta function, which enhances nonlinear chromaticity of the interaction region lattice. Therefore, all the projects have to compensate it. We will review two already present colliders with crab waist collision scheme DAΦNE and SuperKEKB, and three projects: SuperB (Italy), tau-charm (Novosibirsk) and FCC-ee (CERN), explain the common problems of the interaction region nonlinear properties. | ||
