X-Z GEOMETRY PERIODIC PERMANENT MAGNET FOCUSING SYSTEM |
摘要 |
An electron beam focusing system is provided within a microwave amplification tube formed from a plurality of magnetic polepieces interposed by non-magnetic spacers. The tube has an axially disposed beam tunnel which permits projection of the electron beam therethrough. A magnetic field is induced in the tube having lines of flux which flow through the polepieces along a magnetic axis. Heat formed within the circuit flows through the spacers to an external planar surface along a thermal axis, which is non-coincident with said magnetic axis. In an alternative embodiment, a plurality of the tubes can be combined into a common system for focusing a plurality of electron beams. The tubes within the common system share heat sinks which attach to the planar surfaces.
