Abstract:
This project involved the development of a cathode structure using Gated Field Emission Arrays GFEAs that could be modulated at the operating frequency of a magnetron to control electron injection. The goal was to inject the electrons to preferentially form the electron spokes in a 75 kW industrial cooker magnetron. An experiment was developed using the L3 Technologies CWM75KW which can operate as low as 1 kW with an injection current of 150 mA and at a frequency of 915MHz. The experiment replaced the helical cathode in the magnetron with a ceramic based structure that used integrated interconnects, vias, and traces to support 30 GFEA die in a 10-sided configuration.
