DETERMINATION OF THE RADIAL TEMPERATURE PROFILE IN A HIGH-PRESSURE MERCURY DISCHARGE USING THE ELECTRICAL-CONDUCTIVITY

The radial temperature distribution is of decisive importance for the understanding of a high-pressure gas discharge. A new method is propos ed to determine the radial temperature distribution in high-pressure m ercury discharges by means of spectroscopic and electric measurements. An attempt is made to approximate the radial temperature profile upon the wall, apart from the radiating core, by considering a trial funct ion. The coefficients of the function are calculated using the electri cal conductivity profile of the arc.
