Abstract

The Method of Moments (MoM) [2] is widely used for radiation and scattering simulations. LINear ACcelerator (LINAC) such as Radio Frequency Quadrupole (RFQ) [3], [8], can also be simulated with the MoM. Present solvers for LINACs are quite intensive. Faster and more accurate solvers would allow better analyses and potential numeric optimisations of LINACs. In this paper, the MoM is used to simulate a section of the Myrrha's RFQ. First, the MoM is recalled. Then, the low-frequency breakdown [1], [5] is explained. Next, a method based on the loop-tree decomposition is proposed to solve the problem of low-frequency breakdown due to the unavoidable very fine mesh used for the simulation of a four-rod RFQ. Finally, some results obtained with the MoM with Rao-Wilton-Glisson (RWG) [2] basis functions for the Myrrha's RFQ are presented.
