Examination of Excitation Temperature of Vacuum Arc Based on Collisional-Radiative Model

The excitation temperature is a widely measured plasma parameter. In this article, the validity of an excitation temperature measurement is verified using a transition simulation between excited levels based on a collisional-radiative model. The collisional-radiative model calculation was validated by comparing it with the results of a spectroscopic measurement for a 2-kA peak vacuum arc ignited b...
