New Products and Developments: A New Magnetron (2M172A) from Toshiba1

Abstract

AbstractA new magnetron has been developed and introduced into the market for domestic microwave ovens. Fully compatible with the current type 2M172, the new 2M172A has a compact anode with a high thermal endurance, designed by the use of a structural analysis program, (SAP), and a lower power filament designed by a finite element method (FEM). The paper illustrates the design challenges, the evolution and the performance of this series of magnetrons.
