High-current vacuum arc in a magnetic field - NASA/ADS

Experimental results are presented on the volt-ampere characteristics of an arc discharge in a vacuum arc-extinction chamber; the discharge is subject to the effects of a nonuniform magnetic field which has a longitudinal induction component and a radial component. It is shown that a field of this sort with an induction of several hundred teslas causes an increase of current, associated with a ...

A high current vacuum arc in a magnetic field - NASA/ADS

Jan 01, 1978  The current voltage characteristics of a vacuum arc subject to the influence of an inhomogeneous magnetic field containing a radial component B sub r in addition to a longitudinal induction component B sub z were studied. An induction field of several hundred tesla causes an increase in the current as a result of which a section of steeply rising arc voltage is observed, which

Aug 13, 2007  Abstract: The high-current vacuum arcs (HCVA) with high average current densities (J 0 les 3 kA/cm 2) in strong axial magnetic fields (AMFs) B n les 1.2 T were studied. The typical V-shape of Volt-Tesla characteristic (VTC) has been shown to retain in strong AMF and at raising the current density, the quantitative parameters change, though.

High-Vacuum Filters McMaster-Carr

Install these filters between your high-vacuum chamber and the inlet of your pump to remove dust, water vapor, and other contaminants from the system and protect the pump. Commonly used in vacuum-furnace and coating applications, they have a polyester filter element that traps particles as small as 5 microns. All filters have been helium-leak tested to ensure quality.

Oct 03, 2014  Abstract: This paper presents an experimental investigation into the behaviour of metal-vapour arcs in vacuum with and without superimposed axial magnetic fields on copper (99.95 % pure electrolytic) electrodes. Properties of vacuum arcs have been investigated for a discharge current up to about 5 kA. Low-current arcing voltage and average current per spot have been measured.
