| Summary: | Parameters are being studied for a high luminosity e+e-collider operating at the Upsilon 4S that would deliver a luminosity of over 1036/ cm2/s. This collider, called a Super-B Factory, would use a novel combination of linear collider and storage ring techniques. In this scheme an electron beam and a positron beam are stored in low-emittance damping rings similar to those designed for a Linear Collider (LC). A LC style interaction region is included in the ring to produce sub-millimeter vertical beta functions at the collision point. A large crossing angle (+/- 17 mrad) is used at the collision point to allow beam separation and reduce the hourglass effects. Beam currents of about 2.3 A x 1.3 A at 4 x 7 GeV in 1733 bunches can produce a luminosity of 1036/cm2/s. Such a collider would produce an integrated luminosity of about 10,000 fb-1 (10 ab-1) in a running year (10s 7 sec) at the Y(4S) resonance. ©2007 IEEE. |
