摘要： A process for preparing a liquid metal ion source structure, preferably made from graphite, so that it may be wetted with boron-containing alloys. The process first involves the coating the source structure with elemental boron. The boron is preferably furnished as boron powder in a liquid carrier which may then be coated onto the surface of the source structure substrate. The coated structure is heated for a short time to a temperature whereat the source structure substrate and boron form a liquid layer at the surface of the substrate to "boronize" the substrate. The final wetted source structure is achieved by mixing a small amount of free boron powder with the alloy to be ion evaporated (also in powdered form), coating the previously boronized source structure with this mixture and heating the contacted boron-augmented source alloy and source structure to a temperature of at least the solidus temperature of the source alloy, at which point the source structure is wetted. Once wetted, a flow of source alloy toward the emitter tip of the source structure can be established during operation of the ion source. Prior boronizing may be omitted for some boron carbide source structures.

摘要翻译： 一种制备液体金属离子源结构的方法，优选由石墨制成，以便可以用含硼合金润湿。 该方法首先涉及用元素硼涂覆源结构。 硼优选以液体载体中的硼粉末形式提供，然后可将其涂覆在源结构基材的表面上。 将涂覆结构加热短时间至其中源结构基底和硼在基底表面处形成液体层以使基底“硼化”的温度。 最终的润湿源结构是通过将少量游离硼粉末与要离子蒸发的合金（也以粉末形式）混合，用该混合物涂覆先前硼化的源结构并加热接触的硼增强源合金和源 结构至少为源合金的固相线温度，此时源结构被润湿。 一旦润湿，可以在离子源的操作期间建立朝向源结构的发射极尖端的源合金流。 某些碳化硼源结构可能会省略硼化。

摘要： The preferred embodiment of the shielded counter-rotating spinner assembly for microparticalization of liquid consists of two opposed, coaxial, counter-rotating, conical, sharp-edged spinners whose edges are in close proximity and whose outer surfaces are in close proximity with non-rotating shields which extend to the edges of the spinners. The purpose of the shields is to greatly reduce the spinner induced air drafts so that, when liquids are applied to the inside surfaces of the spinners through the axes of the driving motors, the droplets produced on the edges of the spinners are injected into very low velocity air. The benefits of accomplishing this are the realization of very short droplet trajectories, the concomitant reduction in size of a plenum chamber which might encompass the device, the production of dense fogs of liquid droplets, and the ability to efficiently mix a liquid with a gas or to mix binary liquid chemicals together away from the device, but within a restricted volume where the atmosphere may be controlled and the production of solid droplets from the liquid phase through cooling in a finite volume and within a controlled atmosphere.

摘要： Billet (52) of electrically conductive or semi-conductive material has slot (54) therethrough which contains insulator slip (58). In this condition, the ion emitter body (44) is machined with the cylindrical exterior surface (60), conical nose (62) and emitter point (70). The limited electrical path localizes heating under the point (70) and the strong structure of the body permits strong mounting and controlled heat extraction.

摘要： U-shaped billet (52) has a slot (54) cut therein for receipt of a slip of insulator material (56). This body is machined on its front end (64) to produce a narrow bridge (66) of controlled cross-sectional area. Emitter needle (78) is positioned in a bore through the bridge to be heated by current through the bridge. The ion emitter body is rigid and strong to hold the emitter needle in the proper location.
