Description
At the European Free-Electron Laser (EuXFEL) superconducting linac, a revised normal-conducting gun design with symmetrical feed was successfully installed and tested. Thermal expansion of the solid copper body dominantly affects the detuning transients of this cavity. To improve accuracy, and add time resolution over the duration of a pulse, we implemented and tested an observer that estimates the resonance frequency over time using a parameter-identified white-box model of the RF network. Results were validated against forward and reflected power couplers, cavity voltage, and an algebraic stationary approximation.
