Measurement of coupling resonance driving terms in the LHC with AC Dipoles

Transverse betatron coupling in the LHC is measured from Fourier analysis of turn-by-turn beam oscillations excited by AC dipoles. The use of the AC dipole for optics measurements induces a small systematic error which can be corrected with an appropriate data interpretation. An algorithm to apply this correction to the measurement of the coupling resonance driving terms is developed. This paper will review this new algorithm and present results of its application to the LHC.
