We have developed an accurate and efficient analysis method with a multi-conductor transmission line model. This method combines the two-dimensional electrostatic analysis including beams in the transverse plane and the transmission line analysis in the longitudinal direction. The loads are also included in the boundary condition of the transmission line analysis. Calculation of 2D electrostatic fields can be easily performed with the boundary element method. Taking low frequency limit of the formula, we have obtained an accurate expectation of the BPMs of 200 mm diameter at the 3-50 Beam Transport Line in J-PARC. | ||
