Super-B Factory using low emittance storage rings and large crossing angle

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 (10⁷ sec) at the Y(4S) resonance.
