Phys. Rev. ST Accel. Beams 8, 024001 (2005) [7 pages]Measurement of global and local resonance terms
Recently, resonance driving terms were successfully measured in the CERN SPS and the BNL RHIC from the Fourier spectrum of beam position monitor (BPM) data. Based on these measurements a new analysis has been derived to extract truly local observables from BPM data. These local observables are called local resonance terms since they share some similarities with the global resonance terms. In this paper we derive these local terms analytically and present experimental measurements of sextupolar global and local resonance terms in RHIC. Nondestructive measurements of these terms using ac dipoles are also presented. This article is available under the terms of the Creative Commons Attribution 3.0 License.
