Abstract:
1. A detector tube assembly structured to permit electron scrubbing after the assembly has been enclosed and at least partially sealed, the detector tube assembly comprising: (a) a walled container comprising side walls, a formed front end cap, and a formed rear end cap, the front end cap welded to the side walls along a perimeter edge of the front end cap and the rear end cap welded to the side walls along a perimeter edge of the rear end cap; (b) an evacuation tube extending through and welded to the rear end cap, the evacuation tube in flow communication with an interior volume defined within the walled container; (c) a plurality of stacked parallel plate elements positioned within the interior volume of the walled container, the plurality of stacked parallel plate elements separated from each other and from the front and rear end caps by a plurality of spacers, the plurality of stacked parallel plates comprising: (d) a plurality of electrical conductors extending from contact with the plurality of stacked parallel plate elements through the rear end cap; wherein the detector plate may be activated and scrubbed by the electron generating plate as part of the manufacturing process, after the assembly has been enclosed and at least partially sealed, the final evacuation of the assembly occurring through the evacuation tube which is then pinched off to finally enclose and seal the assembly for operation.
