Noninvasively improving the orbit-response matrix while continuously correcting the orbit

Noninvasively improving the orbit-response matrix while continuously correcting the orbit

Based on continuously recorded beam positions and corrector excitations from, for example, a closed-orbit feedback system we describe an algorithm that continuously updates an estimate of the orbit response matrix. The speed of convergence can be increased by adding very small perturbations, so-call...
