Claims

[Scope of utility model registration request]

In an internal magnetic type magnetron with a vertically blown cooling structure in which cooling air is blown in the direction of the tube axis, a notch or protrusion is provided on the end face of the yoke that constitutes the magnetic circuit, and the end of the radiator fin is placed on it to form a gap between the fin and yoke. A magnetron characterized by minimizing the contact surface and greatly reducing heat transfer to the yoke.
