Abstract

A considerable amount of betatron coupling in RHIC was found to originate from the interaction region (IR) triplets. A series of dedicated beam studies was performed with the goal of measuring the coupling errors in the IR triplets. The studies used two different methods: local interaction region orbit bumps and the action jump trajectory analysis. The availability of independently powered skew-quadrupole corrector elements in the triplets allow local, beam-based coupling correction in the RHIC interaction regions using the analysed beam data. We also discuss plans for linear IR correction in the RHIC year 2001 run
