Abstract
Measurements of radiation spectra of a high-current vacuum arc with copper electrodes with high temporal and spatial resolution were done in wide spectral interval. Freely burning arcs and those stabilized with the external uniform axial magnetic field at I les 7 kA, B les 0.2 T were studied. Radial distributions of the excitation temperature of atomic and ionic components in the middle of the arc gap in different modes were obtained. The results were compared to literature data.
