Development and Implementation of Beam-Based Feedback Algorithms for Continuous Wave Superconducting Linear Accelerators

The superconducting linear accelerator ELBE at Helmholtz-Center Dresden-Rossendorf is a versatile light source operated in continuous wave mode. New experiments and beam modes have a higher demand on the beam stability and reproducibility of accelerator settings. These requirements are addressed by an upgrade of the existing digital MicroTCA.4 based LLRF control by a beam-based feedback scheme. This poster gives an overview of the current control scheme, presents the planned beam diagnostics and discusses the possible ways of incorporating the beam-based feedback at the ELBE facility and a future light source.
