A new approach in simulating RF linacs using a general, linear real-time signal processor

The authors describe the implementation of a general, linear model of an RF cavity which was used to develop a real-time signal processor. This device fully emulates the response of an RF cavity upon receiving characteristic parameters (Q/sub 0/, omega /sub 0/, Delta omega , R/sub S/, Z/sub 0/). This processor has the ability to simulate the effect of cavity detuning, beam loading, and finite Q. A brief overview of the relevant theory is presented. The authors focus on the model implementation and conclude with a direct comparison of the results from the mathematical simulations and the hardware simulations. The development of the signal processor to simulate a resonant cavity system which included the effects of beam coupling and input coupling was successful. The results clearly illustrate that there are direct similarities between computer generated responses and hardware generated responses.<>
