The present invention also relates to a magnetic matrix and electron beam source and methods of manufacture thereof.
Claims30
A process of forming metal/ferrite laminate magnet, comprising the steps of:
- (a) forming at least one opening in a metal sheet having a first surface and a second surface,
- (b) securing at least one ferritic layer to said first surface of said metal sheet,
- (c) securing at least one dielectric layer to said second surface of said metal sheet,
- (d) forming an opening through said ferritic layer and said dielectric layer, such that at least a portion of said opening overlaps a portion of said opening in said metal sheet, and thereby forming said metal/ferrite laminate magnet.
