Abstract

Magnetrons can be phase-locked using external systems. An experimental setup using Gated Field Emission Arrays for the modulated electron injection offers a potential solution to this problem by permitting the injection of electrons into the interaction space. Current work focusses on extending previous simulation results into 3-D. A commercially available industrial cooker magnetron (the L3 CWM-75kW) has been successfully simulated by using the 3-D PIC code VSim under the magnetron’s typical operating conditions (18kV, 5A, 1900G, 896-929GHz). The simulation generated results that are consistent with known experimental results in terms of power and frequency.
