Abstract

Atmospheric pressure plasmas can be used to provide a vacuum-atmosphere interface as an alternative to differential pumping. Vacuum-atmosphere interface utilizing a cascade arc discharge was successfully demonstrated and a 175 keV electron beam was successfully propagated from vacuum through such a plasma interface and out into atmospheric pressure. Included in the article are a theoretical framework, experimental results, and possible applications for this novel interface. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.

Electron beam melting at high pressures with a vacuum separator/plasma lens

Conference Hershcovitch, A

Plasmas can be used to provide a vacuum-atmosphere interface or separation between vacua regions as an alternative to differential pumping. Vacuum-atmosphere interface utilizing a cascade arc discharge was successfully demonstrated and a 175 keV electron beam was successfully propagated from vacuum through such a plasma interface and out into atmospheric pressure. This plasma device also functions as an effective plasma tens. Such a device can be adopted for use in electron beam melting.

A plasma window for vacuum{endash}atmosphere interface and focusing lens of sources for nonvacuum ion material modification (invited)

Journal Article Hershcovitch, A - Review of Scientific Instruments

Material modifications by ion implantation, dry etching, and microfabrication are widely used technologies, all of which are performed in vacuum, since ion beams at energies used in these applications are completely attenuated by foils or by long differentially pumped sections, which are currently used to interface between vacuum and atmosphere. A novel plasma window, which utilizes a short arc for vacuum{endash}atmosphere interface, has been developed. This window provides for sufficient vacuum atmosphere separation, as well as for ion beam propagation through it, thus facilitating nonvacuum ion material modification. {copyright} {ital 1998 American Institute of Physics.}

Air boring and nonvacuum electron beam welding with a plasma window

Journal Article Hershcovitch, Ady - Physics of Plasmas

The plasma window is a novel apparatus that utilizes a stabilized plasma arc as interface between vacuum and atmosphere or pressurized targets without solid material. Additionally, the plasma has a lensing effect on charged particles. This feature enables beam focusing to very small spot sizes and overcoming beam dispersion due to scattering by atmospheric atoms and molecules. Recently, the plasma window was mated to a conventional electron beam welder. And, electron beam welding in atmosphere was accomplished with electron beams of unprecedented low power and energy. Weld quality for the nonvacuum plasma window electron beam welding approached the quality ofmore »« less
