Abstract :
Summary form only given. The Relativistic Klystron Oscillator (RKO) is a gigawatt class microwave source that is being investigated within the Air Force Research Laboratory (AFRL). In this talk, results of 3D simulations of the AFRL RKO using the particle-in-cell software ICEPIC (Improved Concurrent Electromagnetic Particle-In-Cell) are presented. Full 3D simulations of the RKO are challenging for a number of reasons, not the least of which is the sheer size of the problem. ICEPIC is unique in its ability to perform very large simulations and is an appropriate tool for solving problems related to the RKO. Other challenges include the correct treatment of emission from the knife-edge cathode and proper modeling of the Q of the RKO cavities.
