Proof-of-concept experimental results stemming from beam simulations for a microfocus electron gun are presented. The simulations demonstrate the potential to produce 4 mA of current through a 40-mu m-diameter spot, at a...
A magnetron concept 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 Lorentz2E. In this approach, f...
