Abstract
Summary form only given. A magnetron structure using field emission cathodes has been modeled with the Air Force Research Laboratory particle-in-cell code ICEPIC and the two-dimensional particle trajectory simulation Lorentz2E1. For the particle trajectory modeling the cathode has a distributed structure comprised of field emitters instead of the traditional thermionic cathode. The cathode is designed with facet plates with slits to protect the emitters. In this work the electron trajectories of the slit structure were modeled with Lorentz2E to study the sensitivity of the device.
