Abstract: An ion accelerator includes: an inner magnet having a channel extending through it in an axial direction; an outer magnet extending around the inner magnet, the magnets having like polarities so as to produce a magnetic field having two locations of zero magnetic field strength. The locations are spaced apart in the axial direction; and an anode and a cathode are arranged to generate an electrical potential difference between the locations.

Abstract: A Hall-current ion source with a narrow ion beam energy distribution is presented. A narrow ion beam energy distribution is provided by a utilization of a multi-chamber anode through which a working gas is applied and delivers a uniform working gas distribution in a discharge channel. Introduction of a working gas through a lower part of anode makes applied electric potential in a narrow area and leading to enhanced conditions for a working gas ionization, high ion beam current, high translation of a discharge voltage into a “monochromatic” ion beam mean energy distribution. A multi-chamber anode with a slit exit for introduction of a working gas into area under anode is utilized to prevent a backflow of insulating and dielectric depositions on anode parts, and under anode area makes a nominal operation with reactive gases without a phenomenon called as “anode poisoning” during long operating hours. The ion source with a shielded Hot Filament design shows very effective ion beam neutralization properties; it produces less heating of the substrate than a traditional one; it has a cleaner ion beam because its beam is not contaminated by the Hot Filament material particles. In the design with two Hot Filaments the ion source operation is extended for tens of hours.

Abstract: A Hall-type ion source for generation of ion beams for technological applications presents itself a hybrid ion source, where properties of closed drift systems and end-Hall ion sources are combined for more efficient operation. An ion source has shorter central magnetic pole than regular closed drift ion source with magnetic screens that provide positive magnetic gradient in an ion source's discharge channel. An ion source with these combined properties has higher ratio of ion beam current to discharge current than end-Hall ion source and wider range of discharge parameters than closed drift ion source.

Abstract: The invention is a Hall thruster that does not have any discharge channel, and magnetic pole piece. The Hall thruster utilizes permanent magnets to produce magnetic field with strong radial component in front of an annular anode, and expands propellant directly into vacuum through the anode acting also as a gas distributor. The invention reduces mass and complexity of conventional Hall thrusters, and offers a radical solution to discharge channel and magnetic pole piece erosion problem.

Abstract: The use of the electride form of 12CaO-7Al2O3, or C12A7, as a low work function electron emitter in a hollow cathode discharge apparatus is described. No heater is required to initiate operation of the present cathode, as is necessary for traditional hollow cathode devices. Because C12A7 has a fully oxidized lattice structure, exposure to oxygen does not degrade the electride. The electride was surrounded by a graphite liner since it was found that the C12A7 electride converts to it's eutectic (CA+C3A) form when heated (through natural hollow cathode operation) in a metal tube.
Abstract translation: 描述了在空心阴极放电装置中使用12CaO-7Al2O3或C12A7的电子形式作为低功函电子发射体。 根据传统的空心阴极器件的需要，不需要加热器来启动本阴极的操作。 因为C12A7具有完全氧化的晶格结构，所以暴露于氧气不会降低电极。 电极被石墨衬垫包围，因为发现当在金属管中加热（通过天然空心阴极操作）时，C12A7电致转变成它的共晶（CA + C3A）形式。
