Description
The control of nonlinear dynamics is essential for achieving the luminosity targets of the Future Circular electron-positron Collider (FCC-ee), particularly in the presence of machine imperfections and strong beam–beam interactions. This contribution presents the first steps toward developing Resonance Driving Term (RDT) correction knobs using a response-matrix and Singular-Value-Decomposition (SVD) approach. The current effort focuses on establishing a simulation framework using the Xsuite, and evaluating the linearity and robustness of the resulting knobs. Preliminary results of their potential impact on luminosity performance, both in an ideal lattice and in the presence of imperfections, are discussed.
