In order to learn more on the physical processes inside the hybrid lithium ion source, a Particle-in-Cell/Monte-Carlo-Collision (PIC/MCC) code is written. This code can simulate the motion of particles in single spatial dimension and three velocity dimensions, abbreviated as 1D3V. In this model, the propagation of the 2.45 GHz microwave is processed using Finite-Difference Time-Domain (FDTD) method, and PIC and MCC method are used to handle the interaction of charged particles with electromagnetic field and collision process between particles, respectively. The validity of the PIC method has been confirmed by the simulation of two stream instability in this work. Moreover, the preliminary simulation results also show that the 2.45 GHz microwave energy can be absorbed effectively by electrons in the presence of an external magnetic field of 875 Gs. And the mirror magnetic field can increase the transverse velocities of electrons.
