Adding an Online Orbit-Response-Matrix Model to the Slow Orbit Feedback at DELTA — •Stephan Kötter and Thomas Weis — TU Dortmund University, DELTA

At DELTA, a 1.5 GeV synchrotron radiation light source operated by the TU Dortmund University, a software upgrade for the slow orbit feedback was introduced. An online fit of the bilinear-exponential model with dispersion (BE+d model) which passively leverages beam position measurements from orbit corrections is currently being added to the system. The fit will boost diagnostic capabilities by supplying estimates of beta functions and phases in both planes. The fitted model can also be used instead of a measured orbit-response matrix for estimating steerer currents for orbit corrections to adapt to changing beam optics without a dedicated orbit-response measurement.
