Magnetrons can be phase-locked using external systems. PIC simulations1 have shown that phase-locking is possible using modulated electron in jection to control the spoke formation. An experimental setup using Gated Field Emission Arrays (GFEAs) for the modulated electron injection offers a potential solution to this problem by permitting the injection of electrons into the interaction space. The present work explores the feasibility of a GFEA-driven industrial magnetron operating at 907 MHz and low power (~1kW). This magnetron will operate at -9kV, 150 mA, and 900G. The design accomplishes the electron injection by arranging 30 GFEA die around a 10-sided (faceted) cathode stripline structure with four delay-line modulated phases. Facet plates provide protection for the GFEA die from ion back-bombardment. The GFEAs under test are high-density die each containing several million emitters based on a design shown to provide emission current exceeding 100 A/cm2 in prior experiments2, Recent efforts demonstrate proof of concept for the GFEA-driven magnetron system by testing these GFEA die in conditions parallel to those required for oscillation of the same magnetron. A phosphor screen at a potential of 300 V was used in a test chamber to study emission current density and uniformity of the GFEA. Both emission current and leakage current were measured, and it was experimentally determined that the requisite 6 mA per die required for oscillation should be achievable under pulsed (10 kHz) conditions with high frequency (905 MHz) GFEA experiments planned. Experimental and transmission line modeling results will be presented.
