The invention relates to a magnetron apparatus with an innovative strapping design that enhances mode separation by increasing the capacitance between straps. The apparatus features sectoral square-shaped metal coverings that enclose parts of the rings closest to the vanes, which reduces electron interference and increases capacitance without physical contact with the straps. Additional straps are added externally to these coverings to further boost capacitance. This design results in more stable and efficient magnetron operation, making it particularly useful in high-power applications across industries such as telecommunications, industrial heating, medical equipment, and microwave engineering.

The invention addresses the issue of mode separation in magnetrons, particularly focusing on enhancing mode separation by increasing the capacitance between straps through novel strapping designs. This improvement is essential to prevent the magnetron from jumping between modes during operation, ensuring stable and efficient performance.
- Increased Surface Area for Capacitance: The invention uses sectoral square-shaped metal coverings to enclose parts of the rings closest to the vanes, increasing the surface area and hence the capacitance between the straps.
- Metal Coverings: These coverings reduce the effect of electrons on the straps and perform dual functions by shorting alternate straps and increasing capacitance without physical contact with the straps.
- Additional Straps: Extra straps are added externally to the coverings to further increase capacitance.
- Strapping Configuration: The straps are configured to pass through hollow spaces within the coverings while maintaining a gap, enhancing the mode separation.
- Shorting Mechanism: At least one set of straps is shorted with coverings, and coverings are shorted with vanes to form an effective anode cavity.
- Improved Efficiency: The novel strapping design allows for more stable and efficient operation, especially in high-power applications.
- Greater Design Flexibility: The ability to increase the number of straps and their strategic placement provides more design options for achieving optimal performance in various magnetron applications.
- The prototype magnetron apparatus includes a cylindrical body, a plurality of vanes, and multiple straps and coverings arranged circumferentially around the vanes.
- The straps and coverings are strategically shorted and spaced to maximize capacitance and minimize electron interference.
- Copper is used for the coverings to ensure high conductivity and durability.
