Method of determination of the electron density in the gap of high-current vacuum arc on the base of continual radiation analysis

In our previous work is shown that in the visual spectral region of radiation of the high-current vacuum arc with copper electrodes there is a spectral “window” that allows to register continuum radiation (including at high-current densities). This fact was used for elaboration of the method of determination of the electron density in the gap of high-current vacuum arc. The method was verified by comparison of the obtained results with known results received by different methods.
