N2 - Particle-in-cell simulations are performed to analyze the efficiency, output power and
leakage currents in a 12-Cavity, 12-Cathode rising-sun magnetron with diffraction
output (MDO). The central goal is to conduct a parameter study of a rising-sun
magnetron that comprehensively incorporates performance enhancing features such
as transparent cathodes, axial extraction, the use of endcaps, and cathode extensions.
Our optimum results demonstrate peak output power of about 2.1 GW, with
efficiencies of ∼70% and low leakage currents at a magnetic field of 0.45 Tesla,
a 400 kV bias with a single endcap, for a range of cathode extensions between 3
and 6 centimeters.
