| Abstract: | A structural model of the focusing section of linear induction accelerator （LIA） is introduced. The 3D numerical model of the focusing section of LIA was built by using a non-uniform mesh model. The field distribution of magnetic components is set to a three~dimensional model based on the independently programed calculation program of the solenoid coil and the magnetic lens. The model simulates the transmission and focusing process of electron in the focusing section of LIA in combination with PIC and FDTD methods. The correctness of the simulation is verified by comparing the results with the conference literature. The results have some significance to the debugging of the focusing section of LIA. |
