            Abstract : 
To maximize the tune space due to momentum spread, an operating point close to the coupling resonance line is desirable. This requires a knowledge of all the coupling sources in the Recycler and a correction system capable of global decoupling to the desired level. We report on the efforts to identify major sources of coupling and verification of the integrity of the powered skew quad circuits used for global decoupling
