Abstract

Improved concurrent electromagnetic particle-in-cell (ICEPIC), developed at the US Air Force Research Laboratory, is a three-dimensional (3-D) particle-in-cell (PIC) code specifically designed for parallel high-performance computing resources. ICEPIC simulates collisionless plasma physics phenomena on a Cartesian grid. ICEPIC has several novel features that allow efficient use of parallel architectures, including automated partitioning, dynamic load balancing, and an advanced parallel PIC algorithm. Even though ICEPIC is still in development, it has successfully simulated real-world high-power microwave (HPM) experimental devices, such as the magnetically insulated line oscillator (MILO) and the relativistic klystron oscillator (RKO), and the results from recent RKO simulations will be presented.
