The Secondary Electron Yield In Multipactor Phenomenon and Python Programming

Multipactor(MP) is an unwanted phenomenon which is occurred in the radio frequency vacuum devices. Research to find a convenient method to lower the MP threshold or move it away from the operational range is an important key in the design of microwave components. In this regard, the accuracy of predicting the MP threshold is essential. In the simulation of MP, the secondary electron yield model is typically built in the commercial code; CST code. The accuracy of the results of MP simulation is mainly determined by the variation of secondary electron yield model. Therefore, in this paper, we calculate the effect of the variation of the secondary electron yield on the results of the MP simulation. For this purpose, the generalized polynomial chaos method is employed using Python programming. This method is based on an orthogonal polynomial expansion. Here, MP in the rectangular waveguide, Cornell Electron Storage Ring input coupler, is studied.
