TI - Analysis of Intensity-dependent Effects on LHC Transverse Tunes at Injection Energy J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - The LHC Run I has provided a huge amount of data that can be used to deepen the understanding of the beam behaviour. In this paper the focus is on the analysis of transverse tunes at injection energy to detect signs of intensity-dependent effects. BPM data, recording the injection oscillations of the operational beams during the ring-filling phase, have been analysed in detail to enable extracting useful information about the tune shift vs. injected beam intensity. The data processing and the results are discussed in detail, including also possible implications for future operation.
