Recent Developments in QuickPIC Open Source*

As a 3D parallel quasi-static PIC code, QuickPIC has been an open source code on Github since 2017 [1]. QuickPIC has been widely used for efficiently modeling the plasma based accelerator problems. Recently, we have merged the field ionization module from the old version of QuickPIC with the open source QuickPIC. We also implement a new field ionization module based on the particle ionization instead of the mesh ionization. The latter one can include mobile ions when simulating the field ionized plasma. We also implement a the new diagnostic for calculating the beam’s betatron radiation in QuickPIC. The beam and plasma particle tracking and the automatic memory reallocation for buffer overflows will be introduced. In addition, we will present the progress on merging the mesh refinement algorithm and the GPU algorithm into the open source code.
