Description
Both 3D quasi-static PIC code and the quasi-3D PIC code using azimuthal decomposition method can obtain 100-1000 times speedup than the normal PIC code when modeling the plasma wake field accelerator. However, when pursuing higher energy and finer physics in the PWFA problems, a code that can cost less computing resources is required. Therefore, we apply the azimuthal decomposition method in the quasi-static PIC algorithm and develop a new code. The code is based on the open source 3D quasi-static PIC code QuickPIC, and it is called QPAD that stands for QuickPic with Azimuthal Decompostion. In this work, we present the basic algorithm in QPAD and some comparisons between QPAD, QuickPIC and a fully 3D PIC code OSIRIS.
