A magnetron is provided including a yoke having an internal space, a first magnet provided at one end of the internal space, a second magnet provided at a second end of the internal space, the second magnet being axially spaced from the first magnet. Further, an anode cylinder that generates radio frequency energy may be provided axially between the first and second magnets, a first pole piece and a second pole piece may be provided proximate first and second openings of the anode cylinder, respectively. Additionally, the magnetron may also include a seal that intercepts external leakage, the seal may have an inward protrusion extending axially towards the anode cylinder; and a choke filter that intercepts external leakage provided proximate the seal.
