Abstract
A cylindrical magnetron having a cylindrical cathode surrounding a cylindrical target. The cathode is without features extending inwards thereof at either end such that the target may be axially removed from or installed into the cathode from either end. The target is positioned and axially retained within the cathode by resilient means operative between the outer surface of the target and the inner surface of the cathode. The invention is especially useful in magnetron assemblies having a plurality of abutting, coaxially disposed magnetrons, wherein all the targets may be removed and replaced from the cathode assembly without requiring disassembly and reassembly of the cathodes.
