Abstract

A "FLIC" dicorotron assembly, as described in U.S. Patent 4,057,723 having a glass coated coronode wire I positioned very dose to or in contact with a shield electrode 2, is disclosed. The assembly is constructed as a cartridge which is entirely self supported and self contained and which can be inserted into end receptacles or end blocks 3. The assembly is better suited for servicing in the field since it would be tested electrically as a unit and would not need testing after installation. The coronode wire 1, shield electrode 2 and two end contacts 4, 5 are mounted on an insulating rod .or tube 6 which is preferably constructed from ceramics or glass. The shield electrode 2 is a tight fitting metal tube which slips over the rod 6 or altern'atively can be constructed from a metallic film deposited or painted onto the rod 6. The cross section of the rod may have shapes other than circular and, for example, might be square or rectangular. The end contacts 4, 5 are of a material similar to the shield electrode and are insulated from the electrode by bare segments of the glass support rod 6. The coronode wire 1 is cemented to the ends of the support and may also be cemented to the shield electrode 2. In combination, the rod 6, wire 1, shield 2 and contacts rC, 5 comprise a cartridge 7 whid fits inside the end blocks 3. The end contacts 4, 5 are biased against metal blocks 8, 9 into which are screwed contact pins 10, 11 for providing electrical potential to the corotron. The mounted assembly is then covered and mounted inside a housing 12.
