【Abstract】 This paper introduces Eulerian angle to express the transformation from the coordinate system of the simple F P cavity to the coordinate system of the AQCORAA cavity and gets the field distribution by performing the integration corresponding to the rotating process instead of the vector algebraic addition. The field distribution is still the Guassian’s, but the peak of the field strength can be regulated to the near exit port. Certainly it is true that this contribution has increased the adjustable degree of the freedom of the interaction regime. Because the field expression obtained here is more concise, it may facilitate the analysis in linear and nonlinear theory of this kind of gyrotron.更多还原
