Spatial and Temporal Temperature Studies of Electrothermal Chemical (ETC) Plasmas

Abstract

Atomic spectroscopy has been used to measure plasma temperatures in the exit flow from a polyethylene capillary. Typical events involve the deposition of about 300 J of energy. Temperature values observed range from 10,000 K to almost 50,000 K, the latter the result of shock wave heating of the supersonic exit flow. Under the most favorable signal to noise conditions, uncertainties are estimated at 5%.
