Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: High precision temperature control of the RF GUN is necessary to optimally accelerate thousands of electrons#R##N##R##N#within the injection part of the European X-ray free-electron laser XFEL and the Free Electron Laser FLASH.#R##N##R##N#A difference of the RF GUN temperature from the reference value of only 0.01 K leads to detuning of the#R##N##R##N#cavity and thus limits the performance of the whole facility. Especially in steady-state operation there are#R##N##R##N#some undesired temperature oscillations when using classical standard control techniques like PID control.#R##N##R##N#That is why a model based approach is applied here to design the RF GUN temperature controller for the#R##N##R##N#free-electron lasers.#R##N##R##N#A thermal model of the RF GUN and the cooling facility is derived based on heat balances, considering the#R##N##R##N#heat dissipation of the Low-Level RF por. This results in a nonlinear model of the plant. The parameters are#R##N##R##N#identified by fitting the model to data of temperature, pressure and control signal measurements of the FLASH#R##N##R##N#facility, a pilot test facility for the European XFEL. The derived model is used for controller design. A linear#R##N##R##N#model predictive controller was implemented in MATLAB/Simulink and tuned to stabilize the temperature of#R##N##R##N#the RF GUN in steady-state operation. A test of the controller in simulation shows promising results.
