摘要：
Precise and fast 3D space-charge calculations have become important for high intensity hadron accelerator design. The PIC method is most frequently used due to its efficiency. This paper introduces a 3D-PIC code that computes the potential of the bunch in the rest frame by means of Poisson's equation. FFT is applied as Poisson solvers. The details and the results are presented as well as error analysis.
