摘要：

Under the condition of the solenoid focusing magnetic fields, Diocotron instability easily forms in the sheet electron beam, which could lead to collapse in beam propagation. This formation of Diocotron instability is presented in detail in this paper by using a three dimensional (3D) particle-in-cell (PIC) simulation. Then the Wiggler field is used to focus sheet electron beam, and the simulation results show that the Wiggler field, to a certain extent, can suppress the Diocotron instability. In addition, the effect of Wiggler field's magnitude and period on the Diocotron instability is also investigated based on the PIC simulation.
