Beam transfer function and stability diagram in the Large Hadron Collider

C. Tambasco, T. Pieloni, X. Buffat, E. Métral
Predictions of transverse instability thresholds in the LHC are based on the computation of Landau damping by calculating the stability diagram (SD). However any modification of the tune spread and/or particle distribution modifies the expected Landau damping in the beams. The beam transfer function (BTF) provides direct measurements of the Landau damping and can be used to understand the limitations of the models.
