Area effect on electric breakdown of copper and stainless steel electrodes in vacuum
TL;DR: In this paper, the breakdown field strength of gaps made with pure copper and stainless steel was investigated and the results showed that the area of effect of E/sub b/ is represented by the area effect of beta /sub l/ and that the vacuum breakdown may be initiated by field emission.

Influence of electrode area on the conditioning effect in vacuum
TL;DR: In this article, the influence of electrode area on the conditioning effect of dielectric breakdown in vacuum gaps was investigated using three types of copper electrodes with different surface areas, and the results showed that the smaller the electrode area, the higher the breakdown voltage.

The Investigation of Copper-Chromium Contacts in Vacuum Interrpters Subjected to an Axial Magnetic Field
TL;DR: In this article, the characteristics of a vacuum arc between CuCr contacts under an axial magnetic field have been investigated, and the arcing voltage of the contacts is lower than that of pure copper contacts by 10-20 V from the measurement of the post-arc current and interruption test results, it was found that the arc concentrates and a part of the electrode melts at a rather low current.
