Italian SuperB General Meeting Report

抄録

A workshop was held in Perugia, Italy, from June 16th to the 19th on the design of a Super B factory, which is proposed to be built in Italy. This machine, called “SuperB,” would re-use many components of the PEP-II accelerator, while the detector would re-use components from the Babar detector. The design luminosity of the machine, however, would be much higher than that of PEP-II: 10³⁶ cm^－2s^－1 at the Y(4s) resonance. In addition, the machine is also planned to be run as a τ-charm factory with a luminosity of 10³⁵cm^－2s^－1 at a ∼4 GeV center-of-mass energy. The machine design also features polarized electrons. The challenges presented by these requirements and the evolving design of the accelerator part of the project (including siting issues) are discussed.
