The Particle-In-Cell (PIC) Code-Framework Warp is being developed by 8 the Heavy Ion Fusion Science Virtual National Laboratory (HIFS-VNL) to guide 9 the development of accelerators that can deliver beams suitable for high energy 10 density experiments and implosion of inertial fusion capsules. It is also applied in 11 various areas outside the Heavy Ion Fusion program to the study and design of 12 existing and next-generation high-energy accelerators, including the study of electron 13 cloud
more &raquo; ... fects and laser wakefield acceleration for example. This paper presents an 14 overview of Warp's capabilities, summarizing recent original numerical methods that 15 were developed by the HIFS-VNL (including Particle-In-Cell with Adaptive Mesh 16 Refinement, a large-timestep "drift-Lorentz" mover for arbitrarily magnetized species, 17 a relativistic Lorentz invariant leapfrog particle pusher, simulations in Lorentz boosted 18 frames, an electromagnetic solver with tunable numerical dispersion and efficient stride-19 based digital filtering), with great emphasis on the description of the mesh refinement 20 capability. Selected examples of applications of the methods to the abovementioned 21 fields are given. 22
