摘要： A wide aperture permanent magnet structure which is useful in creating a highly uniform longitudinal or solenoidal magnetic field in the working region of the magnet and in which the aperture of the structure can be equal in cross-sectional area to the working region of the magnet. The geometry and magnetization direction of the constituent magnets are chosen to maximize the uniformity of the longitudinal or solenoidal magnetic field in the working region of the magnet while minimizing the overall volume and weight of the structure as well as eliminating the need for magnetic pole pieces made of iron or other high permeability materials. The invention can take the form of a cylindrical shell of permanent magnets to create a solenoidal magnetic field, or a parallel surface arrangement to create a longitudinal magnetic field.

摘要： The electron impact surface of an anode/collector is coated with a carbon nanotube coating to reduce the production of secondary electrons and, concomitantly, to suppress the formation of neutral gases and plasma. A carbonizable resin is first applied to the electron impact surface, followed by a coating comprised of carbon nanotubes. The coating is pyro-bonded to the surface by heating the anode/collector to over 700° C. in a non-oxidizing atmosphere. Next, the anode/collector is heated to over 1000° C. while a low-pressure hydrocarbon gas, for example, methane, is flowed over the carbon nanotube coating. The gas decomposes and creates a smooth, non-porous, rigid surface on the carbon nanotube coating. The anode/collector is then heated in a vacuum to evaporate any residual water in the carbon nanotube coating.
摘要翻译：阳极/集电体的电子撞击表面涂覆有碳纳米管涂层以减少二次电子的产生，并且伴随地抑制中性气体和等离子体的形成。首先将可碳化树脂施加到电子轰击表面，然后涂覆由碳纳米管组成的涂层。通过在非氧化性气氛中将阳极/集电体加热至700℃以上，将涂层热粘合到表面上。接下来，将阳极/集电体加热至超过1000℃，同时低压烃气体（例如甲烷）流过碳纳米管涂层。气体在碳纳米管涂层上分解并产生光滑，无孔，刚性的表面。然后将阳极/收集器在真空中加热以蒸发碳纳米管涂层中的任何残留水。
