Abstract :
Based on a coupling-cavity chain equivalent circuit model, a quantitative method is developed to determining the coupling coefficient and frequency deviation of a coupler cavity. This method can simplify the tuning and simulation process of coupler cavity. As an example, we derived the analytical expression of the coupling coefficient and frequency deviation of a coupler cavity of a periodic traveling wave accelerating tube. Compared with the method of R.L. Kyhl, it is consistent when the coupling is correct, and much more, it can calculate the coupling coefficient and frequency deviation when coupler cavity is not matched
