Abstract:
A magnetron include a center plurality of magnets and an outer plurality of magnets arranged around the center plurality of magnets in a shape of two long sections and two shorter turnaround sections. The outer plurality of magnets are configured with at least one region of weaker magnetic field strength in at least one of the two long sections and adjacent to one of the two turnaround sections.
