Ongoing research at the University of New Mexico UNM shows significant improvement in the start and rate-of-build-up of microwave oscillations in a relativistic magnetron driven by a transparent cathode 1,2. Nearly all simulation work on this cathode to-date has been carried out utilizing the MAGIC particle-in-cell PIC code. Simulations of the A6 magnetron with transparent cathode using the 3-dimensional code Improved Concurrent Electromagnetic Particle-In-Cell ICEPIC at the Air Force Research Lab AFRL were carried out to examine the performance of the transparent code and compare with results from MAGIC. Output parameters such as microwave power, microwave frequency and anode current all as function of axial magnetic field are presented and compared with the MAGIC results.
