摘要：
Both the PEP-II and KEKB B-Factories have plans to upgrade their Interaction Regions (IRs) in order to improve luminosity performance. Last summer PEP-II added cooling to the IR beam pipe in order to increase beam currents thereby raising the luminosity. In addition, PEP-II is working on a design that modifies the permanent magnets near the Interaction Point (IP) for an even higher luminosity increase. KEKB is also planning an improvement to their IR that will decrease the detector beam pipe radius. In addition, KEK has a design to increase the luminosity of KEKB to 1x10(35) cm(-2) sec(-1) which includes changes to the IR. PEP-II is also investigating the feasibility of a 1x10(36) cm(-2) sec(-1) luminosity design. I summarize these various upgrades and concentrate on issues common to the different designs.
