Wang, L. A FAST Particle Tracking Code TUP071 wakefield linac collective-effects bunching space-charge 2015 2015-12 This paper presents a fast particle tracking (FPT) code for linac beam dynamics. It includes wake fields, coherent synchrotron radiation (CSR) and longitudinal space charge. We systematically benchmark the FPT with ELEGANT with different physics aspects: pure optics, wakefields, CSR and space-charge forces
