Abstract：
A new idea to compensate the coupling of bePcⅡ will be introduced in this paper. the detector solenoid field in the interaction region will be compensated by six anti–solenoids which are located nearby the interaction point. skew quadrupoles are adopted for the global coupling compensation. the coupling compensation scheme and the method to measure and tune the x–y coupling will be discussed in detail.
