Abstract
Two different diagnostic techniques have been utilized to measure the temperatures of a free-burning argon arc (I = 100 A, electrode gap = 1 cm, pressure = 1 bar). Temperatures above 8000 K have been measured spectroscopically, while off-axis double exposure holographic interferometry has been used to determine the temperatures in the lower-temperature region of the arc. The Abel inversion has been applied to obtain the radial temperature distribution from the path-integrated phase change observed on the hologram. The temperature profile obtained by holographic interferometry has been compared to plasma temperatures as measured by emission spectroscopy at temperatures around 9000 K and also to the plasma temperatures obtained by a numerical model that is based on the solution of a set of conversion equations.
