INTERACTION REGION DESIGN FOR A SUPER-B FACTORY*

We present a preliminary design of an interaction region for a Super-B Factory with luminosity of 1×1036 cm-2 sec-1. The collision has a ±17 mrad crossing angle and the first magnetic element starts 0.3 m from the collision point. We show that synchrotron radiation backgrounds are controlled and are at least as good as the backgrounds calculated for the PEP-II accelerator. How the beams get into and out of a shared beam pipe is illustrated along with the control of relatively high synchrotron radiation power from the outgoing beams. The high luminosity makes radiative bhabha backgrounds significantly higher than that of the present B-Factories and this must be addressed as the design is further improved
