The design philosophy of a family of low cost magnetrons

Microwave heating is now finding its way into the U.S. kitchen. One of the reasons cited for this is the fact that the cost of the magnetron has passed through the cost threshold. Several U. S. companies have worked on low cost designs with varying results. This paper deals with the design philosophy generated by Litton Industries in developing the family of highly reliable, low cost magnetrons for commercial and domestic use. This design philosophy established the electrical parameters and the key facets of construction to assure reliability together with low cost of materials and manufacturing.
