Abstract

As shown in the drawing, a Faraday shield arrangement may be utilized for eliminating dicorotron end arcing. The shield comprises a large inner diameter shrink tubing 10 having a conductive inner wall 12. A small inner diameter shrink tubing 14 is disposed interiorly of tube 10. An electrically conductive wire 16 having a glass coating thereon is disposed interiorly of tube 14. A crimp pin 18 secures one end of wire 16. Pin 18 is mounted on insulating member 20. An electrically insulating member 22 surrounds the entire assembly. In operation, inner conductive wall 12 is electrically connected to crimp pin 18. Thus, wall 12 is at the same potential as dicorotron wire 16. This results in a zero field within the volume enclosed by wall 12. No corona will be formed within this volume. Furthermore, no corona will be formed on the outermost side of wall 12 because its diameter is too large to set up a field strong enough to cause air breakdown at the potentials being used during normal operation of the dicorotron. This structure will eliminate end arcing of the dicorotron wire.
