Radiation Power of a High-Current Vacuum Arc Stabilized by an Axial Magnetic Field in the Visible and UV Ranges of the Spectrum

Abstract

Using a silicon photodiode, we have performed measurements of the power emitted by a vacuum arc in the UV and visible spectral ranges. Measurements have been carried out upon stabilizing the arc by an axial magnetic field in high-current modes with developed anodic activity. The power of radiation emerging from the arc through the side surface is measured. The results obtained show that, when analyzing the energy balance of a high-current vacuum arc, the radiation must be taken into account.
