Abstract :
A 9.3 GHz 6 MeV linear accelerator (LINAC) was designed by using three-dimensional (3D) particle-in-cell (PIC) simulations with 3D time-domain electromagnetic simulations. In the 3D PIC simulations, field data of a π/2 standing wave mode extracted from the 3D time-domain field calculations were injected into a side-coupled LINAC composed of 25 acceleration and 24 coupling cavities. Acceleration of an electron beam of 20 kV, 300 mA in the 3D full LINAC structure was analyzed without spatial or time segmentations, which resulted in maximum energy of 6 MeV and average current of 68.5 mA when 9.3 GHz, 1.6 MW radio frequency (RF) power from magnetron was assumed.
