dc.description.abstract Ongoing research at the University of New Mexico (UNM) shows significant improvement in the start time and rate of build-up of microwave oscillations in a relativistic magnetron that uses a transparent cathode. In recent studies conducted at UNM the experimental results and the results of numerical simulations using the 3-dimensional particle-in-cell (PIC) code MAGIC have shown strong correlation. For this research a 3-dimensional PIC code ICEPIC developed at the Air Force Research Laboratory (AFRL) was used to simulate the A6 magnetron geometry with a transparent cathode. The results were compared with the work done at UNM to test the fidelity of the two simulation codes. Output parameters such as microwave power, microwave frequency, anode current, and leakage current with respect to the axial magnetic field were compared. ICEPIC simulations were run on a parallel architecture with 64 CPUs at a grid resolution of 1mmx 1mmy 1mmz in the 3-dimensional Cartesian coordinate system. These simulations consisted of roughly 6 million active grid cells and 16 million particles. Results indicated agreement between results from ICEPIC and MAGIC to within 20% for standard performance parameters. ICEPIC simulations also confirmed oscillation of the A6 magnetron with transparent cathode at 4 GHz in the 2π-mode.   en_US
