TI - First K-Modulation Measurements in the LHC During Run 2 J2 - Proc. of International Beam Instrumentation Conference (IBIC2015), Melbourne, Australia, 13-17 September 2015 AB - Several measurement techniques for optics functions have been developed for the LHC. This paper discusses the first results with a new k-modulation measurement tool. A fully automatic and online measurement system has been developed for the LHC. It takes constraints of various systems such as tune measurement precision and powering limits of the LHC superconducting circuits into account. K-modulation with sinusoidal excitation will also be possible. This paper presents the first k-modulation and β^{*} measurement results in the LHC in 2015. In addition, the measured beta functions will be compared to results from the turn-by-turn phase advance method.
