Wirenuts (WN parts) consist of closely wound coils which barely slip over the ceramic rods and have been given a kink to insure a bakeout-proof friction fit. (The kink must be supplied by the user according to the amount of friction desired.) Wirenuts may be made from either stainless steel type 304 or from molybdenum, but since high temperature operation is often desired, the wirenuts normally furnished are molybdenum. Products include:Mo-WN-B (20 parts/standard package)Mo-WM-C (20 parts/standard package)

As an aid to joining cylinders to plates, stainless steel wire ring parts (WR parts) are available in several sizes. These should be spotwelded first to the plate (with the cylinder in position), and then to the cylinder. Frequently the cylinders fit so well that the rings are not needed.   Products include: SS-WR-XXXX/031 XXXX = Center Hole Diameter ramgomg from 0.250" to 1.500"All rings have a wire diameter of 0.031".All standard packages include 10 parts.

As a convenient means of joining long metal rods at right angles, special three-coil triplenuts (TN parts) have been produced. The axes of two of the three coils make an angle of about 15 degrees while the third lies between the other two, off to one side, and has its axis perpendicular to the plane containing the other two. To use triplenuts, a rod is first passed through the shorter third coil, then a second rod is passed through the two longer coils (15 degree angle). Pulling the two longer coils into line locks the second rod by friction, and simultaneously reduces the turns diameter on the third coil. This reduction locks the first rod. Ceramic rods may also be locked together using the triple nuts. Product available:Mo-TN-C (5 parts/stan

Stainless steel cylinders (SS-CY) of many diameters from 0.250" to 1.500" and many lengths from 0.1" to 3". Precision-cut lengths of seamless metal tubing used mostly in making electrostatic lenses. They are also used in constructing housings and shielding.Products include:SS-CY-XXX/ZZZ (XXX = outer diameter (in.); ZZZ = length (in.))

Plates which have been bent in the standard manner are called bracket parts (BR parts) and are made in a variety of configurations. Bracket parts are useful in joining plates at right angles, in reinforcing plates to make stronger structures, and in mounting experiments. They are also the basis for several types of clamps.

Stainless steel plates may be positioned using spherical balls (BA parts). Balls allow closer hole alignment than rods, and generate structures which are inherently resistant to twisting. Balls have the disadvantages, however, of being considerably more expensive, harder to assemble, and less flexible with regard to plate spacing.

Spacers (SP parts), with outside diameters of 1.875a and inside diameters of 1.27a, are essentially short tubes which slip over either the ceramic or metal rods, and are intended as an additional way of spacing metal plates. Rigid structures can be made by alternating metal and ceramic spacers on one or more ceramic rods. Since metal spacers are less costly than ceramic spacers, it is frequently desirable to use a long metal spacer in series with a small ceramic spacer to provide wide insulated gaps between plates   Products include: Stainless Steel SpacersSS-SP-B-XXX (XXX for various lengths) (16 parts/std pkg)SS-SP-C-XXX (16 parts/std pkg)Alumina SpacersAl2O3-SP-B-XXX (XXX for various lengths) (32 parts/std pkg)Al2O3-SP-C-6000 (One six in. part/std pkg)Al2O3-SP-C-XXX (16 parts/std pkg)

Flat plates are the basic parts in an eV system. Holes around the outside edge are intended for mounting. The outside borders are designed to allow plates to be mounted side by side in the same plane and still maintain a gap between them for electrical isolation.
