ABSTRACT:
Two or more self-adjusting electrical conductive snubber means are employed in an electron beam device to effect concentricity of the electron gun structure within an encompassing portion of the envelope. Each of the snubbers is a longitudinal resilient metallic member fabricated of flat material and formed for placement on an electrode of the gun structure in an orientation normal to the axis thereof. The central portion of each snubber is an attachment area having like transition portions formed at each end thereof, wherefrom similar resilient lever arms extend in an opposed longitudinal manner, each having a contact element terminally formed thereon. In usage, each of the lever arms is flexed from a relaxed to a compressed position within the envelope in a manner tangential to the positioning electrode to provide an accommodating fulcrum therewith. This self-adjusting fulcrum effects increased pressured placement of each contact element against the surface of the related envelope portion thereby providing concentricity of the gun structure therein.
